Easy to learn

Python has simple to learn syntax which helps beginners to utilize this programming language and has support guide available. See More

Top Con

Slower than alternative languages

Compared to alternatives such as C++, C#, F#, Elixir/Erlang or Go, Python can be sluggish and is often not a good choice for applications where performance is a significant concern. See More

Elias Van Ootegem's Experience

I've tried my hand at python, and I have to say: I'm still baffled at its popularity. It's slow, the tooling isn't great, and the syntax is horrible (I know: "You'll get used to it", and "after a while, the significant whitespace becomes a plus"... spare me the cliches, it's not for me). For quick prototyping, I suppose Python allows you to get started quickly. It's well supported and a great number of people can write it. Those who can't, can at least read it. True, but the performance is pitiful. Because so many people write it, a lot of the code out in the wild really shouldn't exist. The documentation is painful to navigate, the dependency management tool is poor (I mean: PHP has a better tool in composer!). Most of the people who write Python use frameworks like Django, and don't really understand what it does under the bonnet... I've found myself explaining to Python devs why golang yields much better performance. I started off by saying that you don't need something like nginx for a start. Your binary is the server. They seemed confused by this concept. To use python on the back end means you have too much money to burn on CPU power and RAM. Same holds true for any interpreted language in fact. The pythonians (or whatever they call themselves) can say what they want about something not being very pythonic (or "unpythonic"). The fact remains: the language allows you to do things the wrong way. PHP gets a lot of hatred for allowing people to query a database in a template, and rightfully so. Why don't we hold Python to the same standards? PHP is often criticised because it has no real deprecation process. It just ships with one or more replacement modules next to the old one, then at some point it's announced the old module will start issuing E_DEPRECATED notices, and further down the line, the extension will be removed. That is indeed messy. But let's look at Python. How many places still rely on Python 2.x? Youtube (owned by google, who employed Guido Van Rossum, creator of Python) is one. some popular modules only support Python2. How long until the community makes the switch? It's been years now... The language itself feels messy. Passing through the implicit object variable self isn't a huge problem, but it makes it harder to distinguish between static and non-static methods. The "private method by convention" rule is a joke. Python, to me, feels more like a hackers tool. An alternative to the mess that is bash, and more readable than something like Perl. Given the choice, though, I'd rather write a production grade application in anything other than python. Python is a confused language. It doesn't quite know what niche to focus on: is it a language for the web? Django seems to think that it is. Is it for data analysis, machine learning, and science? Others claim that it is. Is it a scripting language that takes away the pain of writing portable Bash, or spending days wading through someone else's Perl scripts? Perhaps. Why not add GUI's to the mix while we're at it... oh, someone did (Pygame, PyGTK, ...). I wouldn't at all be surprised if one of these days we'll see a kickstarter to build a python machine like the good old lisp machines from the days of yesteryear. Some specific oddities about the language that really irked me: Only recently type-hints were added (just checked - about bloody time) No switch-case - a wide-spread construct. This issue is commonly mitigated using dictionaries. If you need a fallthrough case, God help you... Try-catch is again a well-established paradigm, but for some reason, python chose to replace the catch keyword with except. Grammatically, this doesn't even make sense. I read "Try X except Y" to mean: try doing X, except in case Y, implying an exception is checked before the try. I know I'm nit-picking here, but things like this really bug me. No bloody explicit interfaces. Without these interfaces, you have to rely on the hack that is the pass keyword. The pass keyword. I can declare a function, class, or start a block (if, else, except, ... whatever) and tell the interpreter to just not expect anything to be there... just skip it. Save for a few very rare cases, I don't see the point. Even in those rare cases, I'd argue most of those might actually indicate you're doing something wrong to begin with. Like using a language that doesn't have interfaces, for example. Pythonians will say python is strongly typed, and it is. Internally, however, everything is a PyObject. This enables Python to be dynamically typed, but for most use-cases for backend development, you know what types you're dealing with. A statically typed language, like it or not, is safer. Python values are typed, variables are not. I can reuse the same variable for different types. It should be obvious how this makes code more error prone as time goes on. The threading issues are bizarre. Depending on the implementation, you might have things like GIL to contend with. Either way, giving threads to inexperienced developers (like many python devs are) is like taking a group of toddlers on a trip, first to a brewery, then a distillery, to end up at a firing range. It's going to get messy. I mentioned it before, but the syntax... yuck. Significant whitespace is all well and good, but leaving blank lines to make code more airy is important. brackets make it more clear when a block ends (editors even highlight the closing bracket for that reason). No such luck for python devs. See More

Top Pro

Lots of tutorials

Python's popularity and beginner friendliness has led to a wealth of tutorials and example code on the internet. This means that when beginners have questions, they're very likely to be able to find an answer on their own just by searching. This is an advantage over some languages that are not as popular or covered as in-depth by its users. See More

Top Con

Not type-safe

For back-end system development, strong static type checking is extremely important. Without strong static type checking, errors that could have been detected at compile time won't show up until run time, which could have disastrous consequences. See More

Hasnat Babur Raju's Experience

If somehow one indent is deleted there will be disaster! Even an advanced IDE will be unable to format code! See More

Top Pro

Very similar to pseudo-code

When learning Computer Science concepts such as algorithms and data structures, many texts use pseudo-code. Having a language such as Python whose syntax is very similar to pseudo-code is an obvious advantage that makes learning easier. See More

Top Con

Slow to run

Check for example the first result from Google: https://benchmarksgame.alioth.debian.org/u64q/python.html See More

Top Pro

Active and helpful community

Python has an active and helpful community, such as the comp.lang.python Google Groups, StackOverflow, reddit, etc. See More

Top Con

Hard to debug other people's code

As the structure of Python code is based on conventions many developers are not following them and so it is difficult to follow/extract the design of not trivial application from the code. See More

Top Pro

Clear syntax

Python's syntax is very clear and readable, making it excellent for beginners. The lack of extra characters like semicolons and curly braces reduces distractions, letting beginners focus on the meaning of the code. Significant whitespace also means that all code is properly and consistently indented. The language also uses natural english words such as 'and' and 'or', meaning that beginners need to learn fewer obscure symbols. On top of this, Python's dynamic type system means that code isn't cluttered with type information, which would further distract beginners from what the code is doing. See More

Top Con

Speed can matter

Python, like many interpreted and untyped languages, is fairly slow compared to compiled languages like C, C++ or Java. Sometimes this won't matter, but when it does you're talking about twenty times slower than C/C++ and ten times slower than Java. See More

Top Pro

Cross-platform

Installs and works on every major operating systems if not already installed by default (Linux, macOS). See More

Top Con

Significant whitespace

While proper formatting is essential for any programmer, beginners often have trouble understanding the need and lack the discipline to do it. Add to that all those editors that randomly convert N spaces (usually 8) to tabs and you get an instant disaster. See More

Top Pro

Easy to get started

On top of the wealth of tutorials and documentation, and the fact that it ships with a sizeable standard library, Python also ships with both an IDE (Integrated Development Environment: A graphical environment for editing running and debugging your code); as well as a text-based live interpreter. Both help users to get started trying out code immediately, and give users immediate feedback that aids learning. See More

Top Con

Language fragmentation

A large subset of the Python community still uses / relies upon Python 2, which is considered a legacy implementation by the Python authors. Some libraries still have varying degrees of support depending on which version of Python you use. There are syntactical differences between the versions. See More

Top Pro

Comes with extensive libraries

Python ships with a large standard library, including modules for everything from writing graphical applications, running servers, and doing unit testing. This means that beginners won't need to spend time searching for tools and libraries just to get started on their projects. See More

Top Con

Multi-threading can introduce unwanted complexity

Although the principals of multi-threading in Python are good, the simplicity can be deceptive and multi-threaded applications are not always easy to create when multiple additional factors are accounted for. Multi-thread processes have to be explicitly created manually. See More

Top Pro

Can be used in many domains

Python can be used across virtually all domains: scientific, network, games, graphics, animation, web development, machine learning, and data science. See More

Top Con

Might not be very future-proof

Lots of features that will probably be crucial as time goes (good support for parallelism for example) are missing or are not that well-supported in Python. See More

Top Pro

Lots of framework choices

Has many frameworks like flask, django, pyramid, etc See More

Top Con

Confused as to its puprose

Python is used for 1001 different tasks. As a result, the language lacks a clear direction. It seems to be loved by system administrators (because they are done with the mess that is Perl, or Bash). At the same time, a lot of people seem to really love Django. Scientists use Python because it's easy to learn. It seems to have established itself in other fields to do with big data and experimental stuff like machine learning to some extent. The result is a language that feels confused and more of a collection of hackers tools than a purpose-built, razor sharp tool waiting for an expert pair of hands See More

Top Pro

Promotes beautiful code

You are basically put in a situation where you have to write beautiful code, because of the indentation rules. See More

Top Con

Inelegant and messy language design

The first impression given by well-chosen Python sample code is quite attractive. However, very soon a lack of unifying philosophy / theory behind the language starts to show more and more. This includes issues with OOP such as lack of consistency in the use of object methods vs. functions (e.g., is it x.sort() or sorted(x), or both for lists?), made worse by too many functions in global name space. Method names via mangling and the init(self) look and feel like features just bolted on an existing simpler language. See More

Top Pro

Has many libraries for scientific computing, data mining and machine learning

Python is commonly used in data science and has many libraries for scientific computing, such as numpy, pandas, matplotlib, etc. See More

Top Con

Does not teach you about data types

Since Python is a dynamically typed language, you don't have to learn about data types if you start using Python as your first language. Data types being one of the most important concepts in programming. This also will cause trouble in the long run when you will have to (inevitably) learn and work with a statically typed language because you will be forced to learn the type system from scratch. See More

Top Pro

Good documentation

The Python community has put a lot of work into creating excellent documentation filled with plain english describing functionality. Contrast this with other languages, such as Java, where documentation often contains a dry enumeration of the API. As a random example, consider GUI toolkit documentation - the tkinter documentation reads almost like a blog article, answering questions such as 'How do I...', whereas Java's Swing documentation contains dry descriptions that effectively reiterate the implementation code. On top of this, most functions contain 'Doc Strings', which mean that documentation is often immediately available, without even the need to search the internet. See More

Top Con

No delimiters, just indentation

If you forget to indent your code, it will not work properly. Also you can't see the end of the command (";") or the end of the scope ("{" and "}"). This can prove itself very inconvenient for both beginners and experienced programmers. See More

Top Pro

It's really simple

It's very simple for understanding how programming works. See More

Top Con

Not good for mobile development

You can use frameworks like Kivy, but if your ultimate goal is to write mobile apps, Python may not be the best first choice. See More

Top Pro

Supports multiple databases

Top Pro

Advanced community projects

There are outstanding projects being actively developed in Python. Projects such as the following to name a random four: Django: a high-level Python Web framework that encourages rapid development and clean, pragmatic design. iPython: a rich architecture for interactive computing with shells, a notebook and which is embeddable as well as wrapping and able to wrap libraries written in other languages. Mercurial: a free, distributed source control management tool. It efficiently handles projects of any size and offers an easy and intuitive interface. PyPy: a fast, compliant alternative implementation of the Python language (2.7.3 and 3.2.3) with several advantages and distinct features including a Just-in-Time compiler for speed, reduced memory use, sandboxing, micro-threads for massive concurrency, ... When you move on from being a learner you can still stay with Python for those advanced tasks. See More

Top Pro

Static typing via mypy

Python's syntax supports optional type annotations for use with a third-party static type checker, which can catch a certain class of bugs at compile time. This also makes it easier for beginners to gradually transition to statically typed languages instead of wrestling with the compiler from the start. See More

Top Pro

Best chances of earning most money

According to Quartz, Python programming skills on average earn $100,000 per year. Closely followed by Java, C++, JavaScript, C, and R with $90,000 per year and above. See More

Top Pro

One right way to do things

One of the Guiding Principles of Python is that there should be only one obvious way to do things. This is helpful for beginners because it means that there is likely a best answer for questions about how things should be done. See More

Top Pro

Easy to find jobs

Python's popularity also means that it's commonly in use in production at many companies - it's even one of the primary languages in use at Google. Furthermore, as a concise scripting language, it's very commonly used for smaller tasks, as an alternative to shell scripts. Python was also designed to make it easy to interface with other languages such as C, and so it is often used as 'glue code' between components written in other languages. See More

Top Pro

Language of choice for hobbyists

Hackers projects based on platforms like the RaspberryPi almost unanimously use Python. Editors like (neo)Vim allow you to write plugins in Python... you can easily build/extend something if you know how to write this language. See More

Top Pro

Automatically optimized C code

Django specifically uses Cython to turn python code to C code that is super fast. Though python on its own is slow, with cython fast. See More

Great runtime performance

GoLang is compiled language, so it is expected to run faster than interpreted language. GoLang programs may run as fast as ones written in Java. It is just a matter of time when GoLang compiler will beat Java and will compete with C/C++. See More

Top Con

No user defined generics

This means that you can utilize strong typing only as long as you do not need a generic container like for example list. Only ways to deal with it is either code duplication or using interface{} which means that you lose strong typing. See More

Doug Sparling's Experience

Needed something for high traffic website where caching was of little benefit. (Hundreds of thousands of unique requests.) Go may not be the only solution, but I like the language and with Go’s high performance concurrency I got the performance I needed. See More

Top Pro

High level programming language

It makes it easy to learn and the learning curve is friendly for beginners. One can learn the main concepts and ignore unimportant details. While in low level programming languages, like C, one should spend a lot of time on low level details even when developing very basic (web) service. See More

Top Con

Default package manager doesn't allow versioning of libraries

This mean that when using go get we will always fetch HEAD of remote repo. There are however 3rd party solutions for that problem like repository hacks and managers that tries to mimic lock file. See More

Roman Scharkov's Experience

Go provides a very simple mental modal to solve a relatively complex computer programming problem, that is concurrency. Goroutines make asynchronous, non-blocking and highly concurrent code much easier to write and read. Unlike in many other languages running on top of an event loop, like JavaScript for example, where you have to write non-blocking async code properly to not shoot yourself in the foot blocking the single execution thread - in Go writing blocking synchronous code is just fine, because the builtin goroutine scheduler will automagically swap any blocked goroutine for another to not waste any CPU time. What makes goroutines special, is that they are very leightweight compared to regular OS threads we know from Java or C++ and similar, you can spawn millions of them and Go's scheduler will use up all available CPU cores to run as many of them at once as possible. The Go compiler compiles the source code into final machine code which is executed directly by the CPU bypassing any interpreters and virtual machines eliminating the runtime costs of such abstractions as well as any runtime dependencies. Although the compiler isn't probably as smart as a regular modern C or C++ compiler yet, it's compile times are very low and the generated machine code is very efficient making Go blazingly fast, almost as fast as C/C++ (not quite, but still). The built-in concurrent mark-and-sweep garbage collector has it's tradeoffs (like any another GC) but is optimized for latency to minimize stop-the-world delays and does it's job pretty well. The compiler also tries to optimize memory efficiency by trying to allocate as much on the stack (which is also special in Go, but that's a whole other topic) as possible through escape analysis and similar techniques. Besides that, Go offers a strong static type system, supports reflection and encourages duck typing, interfaces instead of classes and composition instead of inheritance. The language grammar is very simple, it makes working in a team of people with different levels of skill a piece of cake. Go has basic support for generics. The builtin map, array and slice containers are fully generic. Documentation is built into the language. Source code comments are automatically transformed into documentation. godoc.org constantly scans for Go repositories and generates public documentation for them on-the-fly. Modular design is achieved through packages, every folder represents a package containing exported and unexported functions, types , constants and singleton variables. All that together with a rich standard library and a high quality toolset make Go a simple, elegant and highly efficient platform for application and systems development. See More

Top Pro

It is supported on all the mainline operating systems and supports cross-compilation

You can compile an executable for linux, windows, OSX, FreeBSD, NetBSD etc. You can easily cross-compile accross platforms. See More

Top Con

Designed to make the programmer expendable

Go was designed for large team projects where many contributors may be incompetent. That Go can still get things done under these conditions is a testament to its utility in this niche. Go's infamously weak abstraction power is thus a feature, not a bug, meant to prevent your teammates from doing too much damage. This also means any team member can be easily replaced by another code monkey at minimum cost. Good for the company, bad for you. The more talented programmers, on the other hand, will be very frustrated by having one hand tied behind their back. See More

Elias Van Ootegem's Experience

As Backend is growing more and more towards containerised micro-services, Golang definitely has got a bright future ahead of it. Having a clean, simple language with the X-platform portability of "ye olde C", and the design team that is focussing the development with networking in mind just makes sense. Your code compiles down to a single binary, that you just drop in a scratch container as your entry point, and job done! That's not to even mention the toolchain. For a language that isn't that old, its toolchain feels very solid, and full-featured. There's go-metalinter to lint-check your code, there's the built-in testing (go test), formatting (gofmt), race detection during testing and/or compilation, profiling, ... it's all ready to be used through a handful of binaries. Java has been around for over 2 decades, and still they haven't settled on a single build tool (maven, gradle, ivy, ...). No language is perfect, but to me, Go strikes a nice balance between cleanliness, not adding bloat (e.g. No classes, but you do have interfaces). Some things take some getting used to, and you might end up abusing them at first (errors as return values, the empty interface type, and race conditions aren't always easy to spot if you're not used to reading go code) See More

Top Pro

Green threads and channels built-in

The system can easily support tens of thousands (user-space) threads, which can communicate and being synchronized using channels. This makes it easy to design a system consuming multiple cores (and being scalable) or making asynchronous I/O. Scalability and asynchronous processing are very important property of systems. Simplicity of working with threads and channels is very important for beginners. See More

Top Con

Implementation of interfaces are difficult to figure out

Finding out what interfaces are implemented by a struct requires a magic crystal ball. They are easy to write, but difficult to read and trawl through. See More

RobustCottus's Experience

Go speed and simple c-like syntax makes it a good fit for our production. See More

Top Pro

The final package contains everything you need to run it

Everything is contained in the executable. Is like you do static linking in C. That means you no longer need to provide external libraries. This also simplifies the installers (if you need them at all). See More

Top Con

Hard to abstract even the simplest notions

Go is famously regarded as very simple. However, this simplicity becomes problematic in time. Programmers who use Go find themselves over and over again writing the same thing from a very low point of view. Domains not already served by libraries that are easy to glue are very difficult to get into. See More

zou ying's Experience

Support multiple cores naturally. Highlight feature of goroutine(corroutine), channel. Wonderful golang ecosystem. See More

Top Pro

Large community

The community is large enough at this point that there are plenty of resources on the web for learning, asking questions, and interacting with many other Gophers. See More

Top Con

Performance slowdown because of indirect calls and garbage collection

Practically no meaningful Go application can be written without indirect function calls and garbage collection, these are central to Go's core infrastructure. But these are major impediments to achieving good performance. See More

Dave Jensen's Experience

Early on in our project we moved from Node.js to Golang. The big concern was that we were losing our expertise in Javascript for something new. After a few weeks on go those conerns went away. The simplicity of the language and the culture of writing simple code hooked us almost instantly. As already experienced programmers we went from beginners to power users overnight (but we're not experts, yet). See More

Top Pro

The go compiler compiles binaries instantly — as fast as a scripting language interpreter

Compiled binaries are fast — about as fast in C in most cases. Compiles on every OS without effort — truly cross-platform compiler. As a result of the fast compilation speed, you can use the gorun program to use go source code as if it was a scripting language. See More

Top Con

Default package manager doesn't allow multiple versions of the same package to be used at once

Default package manager fetch all packages to $GOPATH and use them across all projects which mean that 2 projects cannot use different versions of the same package. However 3rd party solutions exists. This has been solved with the dep tool and semver. See More

Top Pro

Exceptionally simple and scalable multithreaded and concurrent programming

Goroutines are "lightweight threads" that runs on OS threads. They provide a simple way for concurrent operations — prepending a function with go will execute it concurrently. It utilizes channels for communication between goroutines which aids to prevent races and makes synchronizing execution effortless across goroutines. The maximum number of OS threads goroutines can run on may be defined at compile time with the GOMAXPROCS variable. See More

Top Con

Initial setup of working environment is non trivial

We need to set up some environment variables ($GOPATH and adjust$PATH at least). However in most cases it is one-time setup. See More

Top Pro

Support of OOP and duck typing

Interface based polymorphism and structural compatibility of interfaces make it easy to extend the system/application, to reuse the code and to refactor. Basically, it allows to build less coupled architecture. The OOP support is very simple comparing to other OOP languages like Java/C++. It is relatively easy to understand and it almost does not have surprises. OOP in GoLang is a combination of two clear concepts: structs and interfaces. Structs can be just composed, while interfaces defines behavior. It is not only very simple approach but actually very right implementation of polymorphism. In other languages it will take a lot of time to a beginner not only to learn OOP support but also (what is even more important) to learn how to use it and when not to use it. GoLang encourage to use OOP in more right way. Having the minimal and clear concept of OOP, it also makes it very powerful tool of creating abstraction, sometime it is even more powerful than in C++/Java. See More

Top Con

No GUI designer

No forms designer included. See More

Top Pro

Built-in unit testing

The idiomatic approach to writing a Go software project is to perform test-driven development with unit testing. Every source code file should have an associated *_test.go file which tests functions in the code. See More

Top Pro

Simple infrastructure and tooling

Someone may even claim it has too primitive approach, but in reality, when building complex systems, having very well understood infrastructure and tools have a great advantage. For beginners it is even more important that one needs to spend minimum time for learning how to compile and build your first server in GoLang. See More

Top Pro

Great language for building networking services

Go was started as a systems language but now it has fully committed in the niche of networking services. This has been a brilliant move by Go because it allows them to capitalize on the immense talent of the Go engineering team (who are in the most part network engineers). In a world dominated by Java EE and slow scripting language, Go was a breath of fresh air and it continues to be one of the most powerful languages if you want to build networking services. See More

Top Pro

Provides tools for automatically formatting code for your entire software project

This helps keep every programmer on the same page in a project and eliminates arguments over formatting styles. See More

Top Pro

Supports packages properly

Explicit package-level export/import. Package dependency graph (DAG) defines the order of compilation and initialization. Packages help to build the architecture and to deal with the complexity of the system. Packages and clear dependancies makes it easy to understand the system (design). No surprises -- easy to learn and to develop. See More

Top Pro

Strong static type system

Most of errors related to types are detected during compile time. The compiler helps to find "stupid" mistakes on the very early stage, which is very helpful not only for a beginner but for any experienced developer as well. See More

Top Pro

Easy to install and configure; simple to compile software

Go software can be immediately installed, regardless of your operating system, package manager, or processor architecture with the go get command. Software is compiled statically by default so there is no need to worry about software dependencies on the client system. Makefiles and headers are no longer necessary, as the package system automatically resolves dependencies, downloads source code and compiles via a single command: go build. See More

Performance is on the order of C and Java

Go is blazing fast, but easier to write than Python, JS, Ruby, or many other dynamic languages. See More

Top Pro

Supports 'modules' in the form of packages.

Every Go source file contains a package line that indicates which package a file belongs to. If the name of the package is 'main', it indicates that this is a program that will be compiled into a binary. Otherwise, it will recognize that it is a package. See More

Top Pro

Demonstrates a unique, simple concept to object-oriented programming.

All types are essentially objects, be they type aliases or structs. The compiler automatically associates types to their methods at compile time. Those methods are automatically associated to all interfaces that match. This allows you to gain the benefits of multiple inheritance without glue code. As a result of the design, classes are rendered obsolete and the resulting style is easy to comprehend. See More

Top Pro

Supports splitting source code into multiple files

As long as every source code file in a directory has the same package name, the compiler will automatically concatenate all of the files together during the compilation process. See More

Top Pro

Great team working behind it

Go has a solid team of engineers working on it (some of the best networking engineers in the world are working on Go). Up until now, the great engineering of the language has compensated for its lack of power. See More

Top Pro

Multiple variables may be assigned on a single line

This conveniently eliminates the need to create temporary variables. Fibonacci example: x, y = y, x+y See More

Top Pro

Simplified C-like syntax that is as easy to read and write as Python

The language is designed in a manner that seems logical. Syntax is simplified to reduce burden on the programmer and compiler developers. See More

Programmers don't have to argue over what 10% subet of the language to implement in their software project

The language promotes programming in a specific idiomatic style, which helps keep every programmer on the same page. See More

Top Pro

API documentation is rich in content; easy to memorize

Only features deemed critical are added to the language to prevent cruft from working it's way into the language. The language is small enough to fit inside one's head without having to repeatedly open documentation. Documentation is hosted on an official webpage in a manner that is simple to read and understand. See More

Top Pro

Automatically generates API documentation for installed packages

Godoc is provided to automatically generate API documentation for Go projects. Godoc also hosts it’s own self-contained web server that will list documentation for all installed packages in your Go path. See More

Top Pro

Syntax for exported code from a package is simplified to be less verbose than other languages

Any variable, type and function whose name begins with a capital letter will be exported by a project, while all other code remains private. There is no longer a need to signify that a piece of code is 'private' or 'public' manually. See More

Easy interoperability with Erlang libraries

Elixir which is build on top of Erlang's BEAM can directly use Erlang libraries and code, without any trouble. This gives developer access to over 30 years of libraries development for Erlang without any penalty and trouble. See More

Top Con

Requires some knowledge of Erlang

Sooner or later you will be forced to dig into internals of the libraries that you use and some of them are written in Erlang, which has slightly different syntax. However after understanding some Elixir it becomes easier. See More

Top Pro

Great concurrency and scaling

Processes in the Erlang VM are lightweight and run across all CPUs. Thread handling is simpler and more intuitive, and does not require developers to specifically impliment multi-threaded solutions. With multi-core CPUs now mainstream, and octocore not uncommon, this will have a significant effect on performance now, and likely more-so in the future. See More

Some design choices may seem strange

Some design choices could have been a little more appealing, for example: using "do...end" comes natural in Ruby for blocks but Elixir uses them for everything and it looks pretty weird: Enum.map [1, 2, 3], fn(x) -> x * 2 end or receive do {:hello, msg} -> msg {:world, msg} -> "won't match" end See More

Makes developers write optimal code

Rust is a modern programming language written around systems. It was designed from the ground up this way. It's language design makes developers write optimal code almost all the time, meaning you don't have to fully know and understand the compiler's source code in order to optimize your program. Furthermore, Rust does not copy from memory unnecessarily, to give an example: all types move by default and not copy. Even references to types do not copy by default. In other words, setting a reference to another reference destroys the original one unless it's stated otherwise. See More

Top Pro

Compiles to machine code allowing for extra efficiency

Rust uses LLVM as a backend, among other things this allows Rust code to compile down to machine languages. This allows developers to write programs that run as efficiently as possible. See More

For the sake of your code's correctness, you had better write (or have your IDE generate) getters and setters for data fields you expose. And for the sake of safety you should definitely add null-assertions to all non-null method parameters. You also have to catch or rethrow/redeclare all checked exceptions. This, among other things, makes the average Java code extremely bloated and difficult to read. See More

Top Con

Slow to evolve

Java, which is probably the industry's biggest language and platform, is notorious for being slow to evolve. Many useful features, concepts and ideas that the majority of the languages out there have already used for years, are yet to be implemented (or even considered) in Java. Language features which could boost productivity, safety, and overall quality and have proven to do so, are not coming to the next version of Java (probably not the next after that either). See More

Half-baked generics

Type erasure means it doesn't even exist at runtime. The whole generics system is confusing for beginners. See More

Top Pro

Standard-based programming

It's good to have standards for the many tasks needed to do in the web, this makes it easier for you to swap a library without changing much in your code. See More

Top Con

Confusing mis-features

Some features in Java can be quite confusing for beginners. Encapsulation is needlessly obfuscated with a confusing access control model. As an example, the "protected" keyword not only grants access to child classes, but to the entire package. Since small programs are written as one package, it becomes functionally equivalent to "public". In OOP, everything is supposed to be an object, but, in Java, primitive types such as integers, booleans and characters are not, and must be handled as special cases. Java continues to lack many high-level features, and, particularly prior to Java 7, compensated by adding confusing Java-only features, such as anonymous subclasses. Some example code is unreadable without knowing a special-case feature, libraries differ in style based on when they were released or what platform they target(e.g., Android vs. Desktop), and some solutions just aren't available on some platforms. See More

Top Con

Worst-of-both-worlds static type system

It's just barely good enough to make decent IDEs, but it's not at the level of Idris or even Haskell. For large enterprise projects, the IDE support is important, but the static typing in Java just gets in the way for the smaller projects beginners would start with. Python is duck typed and this makes small programs easy to develop quickly, but the price is that you have to write unit tests to avoid breaking larger programs. In contrast, you can be reasonably certain that a program that actually compiles in Idris does what you want, because assertions are built into the powerful type system. Java can't make that claim and still requires unit tests. Java has the worst of both worlds because of its poor static type system. See More

Top Pro

Platform Independent

Because of the Java Virtual Machine, the Java programming language is supported wherever a JVM is installed. See More

Top Con

No top-level functions

Sometimes the appropriate abstraction is just a function. In Java everything happens within a class. If all you want is simply a function, then you first need a class. This class should act as a container or a namespace for your function. Therefore it should not be instantiated, so you should make it final and its constructor private. Maybe make the constructor throw an exception for good measure. Within this class you can declare your function as a static method. Now, the class we declared (usually referred to as a utility class or a helper class) can hardly be considered a class anymore. There is no way to make an object out of it and it exists merely to act as a namespace for your function(s). See More

Strong typed language with an excellent compiler

You always know that if it compiled then you won't have big surprises when running See More

Fantastic IDEs

Because Java is statically typed, integrated development environments (IDEs) for Java can provide a lot more feedback on errors you will encounter. Java IDEs can give you specific errors in the location where they occur without having to run the code every time. This makes is faster to debug and learn from your mistakes. IDEs also have extensive auto complete capabilities that can help you learn the programming libraries you are using faster and tell you what functions are available. See More

Most commonly used language in industry

Java is one of the most popular languages in industry, consistently ranking either first, or occasionally second (behind C or Javascript) in terms of usage. Polls (see sources below) show it to be consistently in high demand, particularly as measured by job board postings. This makes Java a great time investment, as you will be easily able to get a job utilizing your skills, particularly as those Java applications in production now will continue to need maintenance in the future. It also results in great support for tools and plenty of computer science books, example projects and online tutorials. See More

Consistent programming standards

Most Java code follows very standardized coding styles. This means that when you're starting out, there are fewer questions about how you should implement something as the programming styles and patterns are well established and consistent. This consistent style means that it's often easier to follow others' example code, and that it's more likely to meet at least a certain minimum standard of quality. This discipline with consistent stylistic standards also becomes useful later, when collaborating on projects with larger teams. See More

Too easy to write multithreading apps that are buggy

Many web frameworks or GUI libraries will push novice users to writing multithreaded code, which leads to frustrating race condition bugs. Other languages with multithreading push users towards safe constructs, like passing messages and immutable or synchronized containers. But in C# the data structures aren't synchronized by default, and it's easier to just set a field and observe the result from another thread. See More

Top Pro

Awesome IDE for Windows

On Windows, Visual Studio is the recommended C# IDE. It provides a very flexible GUI that you can rearrange the way you want and many useful features such as refactorings (rename a variable, extract some code into a method, ...) and code formatting (you can pick exactly how you want the code to be formatted). Visual Studio also highlights your errors when you compile, making your debug sessions more efficient since you don't have to run the code to see the mistakes. There's also a powerful debugger that allows you to execute the code step-by-step and even change what part of the code will be executed next. In addition to giving you all the line-by-line information you'll need in a hassle-free manner, Visual Studio has stuff you can click on in the errors window that will take you to the documentation for that error, saving you several minutes of web searching. In addition to all of this, Visual Studio has an intuitive, intelligent, and helpful graphical user interface designer that generates code for you (the best of WYSIWYG, in my opinion), which is helpful for new programmers. Being able to create a fantastic-looking UI with one's mouse and then optionally tweak with code helps make programming fun for beginner developers. Visual Studio also has the best code completion --Intellisense is every bit as intelligent as the name says it is. It, as well as VS's parameter hinting, is context-, type-, user-, and position-sensitive, and displays relevant completions in a perfectly convenient yet understandable order. This feature allows a new programmer to answer the questions "What does this do?" and "How do I use it?" right then and there rather than having to switch to a browser to read through extensive documentation. This allows the programmer to satisfy their curiosity before it is snuffed out by several minutes of struggling through exhaustive documentation. And for the more adventurous and text-ready developer, Microsoft does the best job of ensuring that everything, from interfaces and wildcard types down to Console.WriteLine("") and the + operator, is well-documented and easy to understand, with relevant and well-explained usage examples that manage to be bite-size yet complete, simple yet truly helpful. The reference site is easy to navigate, well-organized, clean and uncluttered, up-to-date, and fresh and enjoyable to look at, and every page is well-written with consideration for readers who are not C# experts yet want to read about changing the console background color. The best part? It's free! Visual C# Express contains all of the features described above, at zero cost. If you are a student, you can probably get Visual Studio Professional from your university, which also includes tools for unit testing and supports plugins. See More

Top Pro

Highly transferable concepts

Haskell's referential transparency, consistency, mathematics-oriented culture, and heavy amount of abstraction encourage problem solving at a very high level. The fact that this is all built upon little other than function application means that not only is the thought process, but even concrete solutions are very transferable to any other language. In fact, in Haskell, it's quite common for a solution to simply be written as an interpreter that can then generate code in some other language. Many other languages employ language-specific features, or work around a lack of features with heavy-handed design patterns that discourage abstraction, meaning that a lot of what is learned, and a lot of code that is needed to solve a particular problem just isn't very applicable to any other language's ecosystem.

Ruby is one of the most popular languages for developing web sites. As a result, there's an abundant amount of documentation, sample code, and libraries available for learning the language and getting your project up and running. The most popular features are just 'gem install' away. Additionally, it is easier to find Ruby jobs because of this. See More

Top Con

Meta-programming causes confusion for new developers

The ability for libraries to open classes and augment them leads to confusion for new developers since it is not clear who injected the functionality into some standard class. In other words, if two modules decide to modify the same function on the same class can introduce a number of issues. Mainly, the order in which the modules are included matters. Since you more or less can't tell what kind of "helper" functions a module might write into any class, or for that matter, where the helper function was included from, you may sometimes wonder why class X can do Y sometimes but not at other times.

Undefined behaviors and weak limited type safety

Undefined behavior in a program can cause unexpected results, making it hard to debug. With UB, program behavior may vary wildly depending on optimization settings. There are many cases that invoke UB, such as signed overflow, invalid dereferences, large integer shifts, uninitialized variables, etc. C++ allows for non-type safe operations such as logic errors, wild pointers, buffer overflow, etc. UB and type safety issues create a large number of bugs and security vulnerabilities.

No two programmers can agree on which 10% subset of C++ to use

C++ is such a huge and complicated language, that programmers have to learn a disciplined subset of it to reliably get anything done. The problem is, no-one can agree on which subset to use and they can't understand each other. See More

Top Con

Module system is not great

C++ uses the #include mechanism provided by C. Which unfortunately is a poor way of accessing the API of a library. Some of the reasons why the module system is weak are: Compile time scalability: The compiler must preprocess every header included in a file, and every header included in those headers. This process must be repeated for every translation unit in the program. As can be imagined, this doesn't scale very well. For each header added you are increasing the compilation time exponentially. Fragile: modules included are treated as textual imports by the compiler. This causes all sorts of problems since they are subject to any macro definitions in the time of the inclusion. If any of these macro definitions collide with a name in the library it can break the library API . See More

Top Con

Undefined behavior

Subtle errors can render the entire program "undefined" by the complicated C++ standard. The standard imposes no requirements in such cases. Thus C++ compiler writers are free to ignore the existence of such cases and Bad Things are prone to happen instead. Even experts can't reliably avoid undefined cases in C++, so how can beginners be expected to do so? See More

Top Con

Huge language gets in the way of learning

C++ is such an atrociously over-complicated language that its learning curve may get in the way of learning fundamentals. Learning C++ well is a ten-year project, and even experts are frequently surprised by the language. See More

PHP

Top Pro

Widely used for websites

PHP is the quasi-standard for backends for web applications and used by most of all websites. Many popular CMS are built with PHP, e.g. Wordpress, Drupal and Joomla. See More

Top Con

Poorly designed language

Despite its widespread use, PHP is generally looked upon poorly from a design point of view. The consistency of function names and function argument order, lazily and borderline non-functional implementation of object oriented programming, can only receive requests via POST methods, slow version adoption (the PHP you learn right now may not work on every webserver you'll work on), and a focus on "hacking things together" rather than "doing it right". These are all very common complaints when it comes to working with PHP. While not a bad language to learn, PHP is not at all a good language to learn first, as it will probably teach bad habits.

Very slow compared to alternatives

Compared to alternatives like Exilir and Go-lang, which provide comparable functionality, even the latest versions of PHP are vastly slower than their competitors. The difference is so significant that it has the potential to bottleneck even modestly sized applications and lead to highly significant increases in hardware costs, even with well-written code. PHP's syntax is also highly permissive of non-optimized code which can further exacerbate this issue. See More

Thousands of tutorials and courses to get you started quickly

There are thousands of tutorials available and most online course providers offer PHP courses too. Learning the language will not fail because of missing reading. See More

Top Con

Often awkward setup

PHP setup can be awkward and differ significantly on different platforms in ways that are not always entirely justifiable. Often old versions of PHP (5.6) will conflict with newer versions (7.x) when working with legacy installations, and configuration of php-fpm when working with nginx can be overly complex for first-time setup, particularly for small to mid scale projects. Because the language has grown as a patchwork, different PHP documentation often provides conflicting and out of date info, which can cause system-wide problems if implimented by someone of junior or even intermediate skill. While this is also true of other languages, it is especially so of PHP, and significant development time is often lost on issues that sensible defaults would fix. While the Laravel framework, particularly in concert with Homestead, does mitigate these issues, it is by no means a universal panacea, as it will not be possible to impliment in many real-world situations.
