Pascal / Object Pascal

Top Pro

Understanding of basics

Because of the verbosity and easy syntax, Pascal language is relatively easier to be learned and understood, even for someone who has no programming knowledge. It's said that Pascal code —if written well— is like reading pseudo code. See More

Top Con

Niche language

Most use of this language will be found in jobs supporting legacy code. It will be hard to find things to do with this language outside of that niche. See More

Top Pro

Clear syntax

Pascal's syntax is clear and concise, for example: procedure test(); begin DoSomething(); end; See More

Top Con

No up-to-date version of language standards

In 1983, and update in 1990, the language was standardized with two standards: ISO/IEC 7185:1990 Pascal and ISO/IEC 10206:1990 Extended Pascal. However, Object Pascal extensions to the language have no official standards but in 1993, a draft proposal for object oriented Pascal standard was re; for review purposes only. There are no standards for modern features and enhancements, thus various Pascal dialects like Delphi or HP Pascal has their own enhancements and features. See More

Top Pro

Easy

Pascal / Object pascal was used in schools during the 2000's to teach kids the basics of object oriented programming. See More

Top Con

Effectively obsolete

While this may have been an ok choice 25 years ago, it no longer is. Consider Python, Go or Clojure. See More

Top Pro

Flexible

Using the Free Pascal Compiler (the main Pascal distribution) you can code in a language that can be procedural and imperative now, but it can became object-oriented simply adding a directive at the start of the source See More

Top Con

Unnecessary heavy syntax

Begin.. end. Pascal would have been great with curly braces.. but then again, that's what C is for. It's an academic language which was used in the past, but not much anymore today. See More

Top Pro

Cross platform

Pascal development tools are available almost on every available platform, especially using Free Pascal. Pascal language is available on desktop like Mac, BSD, Linux, Windows, Solaris, etc.; on mobile like iOS, Android, etc.; also on managed environments like Java Virtual Machine (JVM) and .Net/Mono framework . There are even some Pascal to JavaScript transpilers such as Smart Pascal, so you can write client side web app using Pascal as well, if you really want to. See More

Top Con

All variables, types, constants and functions must be declared at the beginning of the code

Top Pro

Tons of academic reading

Being known as the programming language for education, especially in the 90's, there many academic reading and tutorials available on the internet. See More

Top Pro

Fast compilation

The compiler is fast, really fast. Compared to C/C++, the delphi compiler is designed to compile a decent sized desktop application in seconds rather than minutes. See More

Top Pro

Rich existing libraries

Both shipped with implementations and spread all over the web. Both natively written or bindings to libraries written in other languages. Typically to build non-trivial applications there's no need to surf the web as many things are implemented already. Streaming, output templating, socket & networking, web, database, image manipulation, high performance graphics, (de)compression, (de|en)cryption, regex, unit testing, json manipulation, google API, indexing, multithreading, external process management, the list just goes on and on! See More

Top Pro

Enforces good programming practice

Numerous strong compile time checks with optional runtime checks ensure one doesn't do stupid things and even when one does (because the compiler can't prove it at compile time), the binary will check and report it at runtime. Correct modular programming implementation with proper namespacing, no file inclusion hack. See More

Top Pro

Easy GUI creation

Visual Basic may have predated Delphi but Delphi was the ground breaking visual designer which set the standards expected today by most GUI developers. Its rich component set was well designed, structured and extensible, it even has the ability to display live data from the attached database in its data controls. See More

Top Pro

Still active

From the early roots of Pascal, Delphi has been developed and is still actively supported. It is used in many desktop applications today, and even supports multi platform coding. See More

Top Pro

Reliable language and code base

Most code from the Turbo Pascal days in the 80s still compiles, yet the language has since been adapted and extended with modern concepts, introducing OOP and interfaces, exception handling, native Unicode support, anonymous methods, generics, ARC and more. See More

Top Pro

Language depth

Object Pascal is being used to write custom kernels (Ultibo) and operating-systems for various ARM boards. So the way you work with the code scales from low-level to pure OOP high-level. Object Pascal has the same level of depth that you find in C/C++ but with added productivity. See More

Top Pro

Incredible GUI design tools

Lazarus and Delphi are both incredible GUI design tools, making rapid development a reality. Making changes to a GUI doesn't mean switching tools or waiting for things to load, it's right there as part of your core tools. See More

Assembly

Top Con

Difficult learning curve

Starting off as a beginner with assembly language could prove very daunting. I suggest learning a high level language first (e.g. C) to get a good grasp of programming - especially dealing with bits, bytes, numbers, accessing memory with pointers (which is why I suggest C). Then once that person is comfortable writing C (or whatever high level language) programs, they would find moving to assembler a little less of a "What the hell?!!!" experience. See More

Top Pro

Low Level - it's how the computer works

One of the best ways to learn how a computer actually works is to work your way up from lower level abstractions. Assembly, being only a level above machine code, is low enough level to make it clear how the computer is actually performing a computation, including code flow and loops, but high enough level to not be excessively tedious for the type of small projects that a student would do at the beginning of their first programming class. Use of an assembler with macros can stretch this even a bit further. See More

Top Con

Rarely a requirement or used in professional employment

(except for experts, which will outperform you in assembly language and execution speed on any day of the week, simply because they have full control of the processor.) See More

Top Pro

You must look into it if you really want to understand what computers do

There is no other way to understand a processor, so dig in. See More

Top Con

Not very portable

The instruction set may change depending on what CPU architecture is being used. Also, there will be some differences in implementations due to different assemblers being used, such as with changes in OS. See More

Top Pro

Naturally creates fast and small programs

Because of its natural syntax and low-level nature, assembly language programs are typically really small and fast. Unlike other programming languages, in assembly language it is really hard to create a slow and over-bloated program. See More

Top Con

Language for those sadists that like pain

Not recommended as a first language. However, in small doses to show how higher level code is executed, can be of some value. Is also a language that will take a longer time to learn or finish projects with, so usually not for those who are in a hurry to get anything in particular done. See More

Top Pro

Useful for embedded systems

A curriculum that involves an embedded component, such as an Arduino or a Raspberry Pi, can encourage students by allowing them to immediately connect their work with 'real systems'. Assembly is the ideal language for getting started with and understanding these devices, and since Assembly can be called from C, the code will still be useful if students move on to C later in the program. See More

Top Con

Hyperspecific syntax isn't a good first step to learning other modern languages

Top Pro

Uniform syntax

Assembly language syntax is relatively uniform, and so there's less room for a student to get confused by obscure characters, or miss some meaning implied by structure, such as with scoping rules, or call-by-name/value/reference semantics. While there may be a lot of mnemonics to look up, most work involves only a very small subset of them. See More

Xtend

Top Con

Difficult to configure in Android Studio

Top Pro

Ruby-like syntactic conveniences

Lambdas are written like Smalltalk's blocks. If it's the last argument, it can go after the parentheses like Ruby's blocks. Parentheses on method calls are optional. See More

Top Con

Slower compilation

Unlike most JVM languages, Xtend compiles to Java rather than directly to JVM bytecode. So you have to compile everything four times for Android: from Xtend to Java, from Java to JVM bytecode (.class files), from .class to .dex bytecode, and then AOT compilation from .dex to native ARM upon installation. This can really slow down development and testing vs a more interactive language like Clojure. See More

Top Pro

Type inference

It uses Java's static type system, but you don't have to declare the type of everything all the time, since the Xtend compiler can usually figure it out. This also dramatically cuts down on Java's infamous verbosity. See More

Top Pro

Code runs just as fast as Java

Because Xtend relies heavily on JDK and Android classes, it runs just as fast as native Java code. See More

Top Pro

Easy to switch back to Java

Xtend is a low-risk option. Because it compiles to human-readable Java, if you decide you don't like it for your project, you can just switch back to Java without losing your work. See More

Top Pro

Extend even library classes with new methods

This is where it gets its name. You can open classes and add new methods, kind of like Ruby. (Of course this has to be compiled to Java, so really it lives in a kind of helper class.) See More

Top Pro

Succint

Uses functional features ,which are very concise and idiomatic. Plus it has annotations, which cuts down on the Java boilerplate. See More

Top Pro

Better defaults than Java

Methods are public if you don't specify, and fields are private. Locals declared with val in Xtend are final in Java. This dramatically cuts down on Java's infamous verbosity. See More

Bash (Bourne-Again SHell)

Top Pro

Default shell on most systems

Bash is the default shell on virtually every UNIX system. Making it very portable across different systems and once you get used to it, you can use it everywhere. See More

Top Con

Extremely complicated and inconsistent rules

In Bash, exceptions are the rule, not even all being described by the main page. There are a grand total of 5 different ways of quoting, sometimes even when one does not want to, for instance in command substitutions. These are all based around preserving the literal meaning of every character, with an exception list. There is even an exception list to the exception list in 4 of the 5, regarding how the backslash behaves! The behavior of the backslash is also one of the quoting rules, so naturally, it also has an exception in how it works when it stands before a newline as compared to other characters. Bash has several layers of interpretations, all to be kept in mind: The ~ expands to the home of the current user. So if you store it in a variable, can you use it that way? Nope: tilde expansion comes before variable expansion. Aha, so that's how it works! Then, since applying quotation happens after redirections are set up, it must mean that redirecting within quotes works, right? Nope: there is an exception! If a redirection symbol is not quoted, quotation around the symbol is observed, but is not removed. So, since variable expansion also comes after setting up redirections, and no exceptions are described here in the man page, getting the name of a file from a variable and using it as a target should not work, right? No: redirection does not actually take place when the symbols are being read, the symbols are merely removed and are noted for later, right before when the actual command runs. Apart from 5 types of quotation, there are basically 2 quoting phases, 2 word splitting phases (with only one being controllable), and a tokenization phase on top of that. If you have a command, it could be an alias, a special built in, a non-special built in, a symbolic link to a file, a regular file, a function, with different rules regarding how they can be overridden, if redirection happens before or after arguments have been passed (what does "time my_command 2>&1 >log_file" do?), etc. This list is admittedly long, but it doesn't even scratch the surface of the bloat, complexity and inconsistencies of Bash. See More

Top Pro

Plenty of examples and tutorials

Since this is very mature shell there is a lot of great examples and other resources describing how to do almost everything. See More

Top Con

GPL3 is not compatible with Apple's lawyers

Apple, one of the largest distributors of UNIX systems, only ships an ancient version of bash that predates the iPhone. No one knows why as Apple hasn't said, but the version Apple includes in MacOS is from right before the license was updated to version 3 of the GNU GPL (General Public License). Other major companies (IBM, Microsoft) have had no problem shipping the latest version of bash, so it's unclear what Apple's lawyers are averse to. The GPL has always said that if you distributed a program, you granted everyone the right to use it freely. The biggest change in version 3 was the addition, "...and that includes software patents." This was necessary because back in 2006 Microsoft was demanding that any company that uses Linux pay them or get sued for infringing on their patents. They even took some companies, like TomTom, to court. No software which can be restricted retroactively like that is truly free, so GPL 3+ includes a clause saying that if you distribute the program, then you are also granting license to any patents you own that are necessary to run it. What patents Apple has that bash could possibly infringe on is a mystery, but the bigger question is, Why does Apple even care? So what if they are granting people the right to run bash without being sued by Apple. It's not like they were planning on doing that, right? Even though it is not bash's fault that it is not Apple Lawyer-approved, this is a CON for it because a lot of people use Apple products. While there are methods like brew to install a current version of bash, Apple does not make it obvious to their customers what they are missing. See More

Rich scripting capabilities on a single line

Want to run something 5 times? Write a throw-away loop: for i in 1 2 3 4 5; do date; done If you need it 100 times? Not a problem: for i in {1..100}; do date; done or: for ((i=0; i<100; ++i)); do date; done How about emailing yourself when remote server is back online? Sure thing: while ! ping -c1 example.com &>/dev/null; do date; sleep 5; done && mailx -s 'server is back!' me@myself.com See More

Top Con

Compatibility can be a curse

One of bash's claims to fame is compatibility with previous versions of itself and historic shells. But, doing that means that new features are often written in tortured, awkward syntax that is not easy to learn. For example, bash uses the POSIX way of doing arithmetic: to add 5+3 you must put the numbers in double parentheses with a dollar sign at the start: x=$((5+3)). It is true that many shells suffer from this same CON, but since bash is such an important shell, it has less wiggleroom to ditch clunky ideas that might break existing scripts. See More

Top Pro

Emacs-like keyboard control

Top Con

Filename expansion is not consistent

filename expansion is not consistent. "echo *" will print the names of the files in your current dir, if there are any... and will print "*" if there are none. See More

Top Pro

Rich built-in features

By default, there are many built-in features. They make really complex and reliable programs possible. In comparison to dash, for example, you can do the same tasks in less time and fewer lines of code. See More

Top Con

Non-intuitive shell expansion in for loops

If there are no .sh files, this will print mask itself: for filename in *.sh; do echo $filename done See More

Top Pro

Variables and aliases are listed the way they are built

alias and set will list aliases and variables in a format that can be run directly with no modifications. Even if the values contain \n. This is handy if you want to modify a value. See More

Top Con

No out-of-the-box command autocompletion

To have command autocompletion in bash you need to install third-party plug-ins. See More

Top Pro

Recursive globbing

ls **/*.log for example is supported by Bash if you set shopt -s globstar. See More

Top Con

One of the most dangerous languages around

What it is mostly used for are file system operations. Guess what it is bad at? Operating on files. It automatically splits and carries out filename expansion on every single string resulting from variable expansion and command substitution unless quoted, by default on whitespace, whilst spaces are very common in filenames. Before that, it even does pathname expansion, so woe to anywone who does not want to actually operate on files, but has a globbing metacharacter stored anywhere in a variable. This means what you store in a variable is not going to be what will ACTUALLY be accessed. If an empty variable is unquoted, it disappears completely due to word splitting, sometimes leading to applications signalling a missing parameter at a wrong position. If quoted however, said variables cannot be iterated over in a loop, no matter what character one uses for word splitting. If you use any globbing pattern with a command, be sure to use -- after the option arguments or if none are present, before starting the pattern with a mandatory ./ Otherwise, another Bash script run gone wrong or a hacker can create files named like an option ("-f", for instance) and your program will happily accept it as such, if it results from globbing. For interactive use, it is convenient. For programming, it is a no-go. See More

Top Pro

Man page is a trove of wonders

While the manual "page" is nearly a hundred pages long, it is actually surprisingly succinct and stuffed with good information. It is often better than Googling for answers when writing shell scripts. The way it is written makes it easy to stumble upon useful new programming features just by flipping through it . NOTE: If you find it dense and hard to read at the command line, look for the PDF version. See More

Top Pro

vi mode is more comprehensive than on other shells

Vi editing mode works without a glitch. "_" will print you the last argument of the latest command (zsh won't). VI mode is fast off the bat - You don't have to reset any variable (like "KEYTIMEOUT" in zsh) for that. See More

Top Pro

Copyright license is GPL 3+

Bash is licensed under the GNU General Public License ≥3, which gives much stronger assurances that the right to use it can't be restricted. For example, Microsoft would not be able to claim in court that, even though they've distributed Bash with the GPLv3, a license that explicitly grants people freedom, now Bash is essentially proprietary due to software patents and everyone who uses Bash owes them money. (This may sound ludicrous to those who were not alive when Microsoft tried a similar scheme against Linux fifteen years ago). The GPLv3 is a license that reflects the genuine ethical issues that arise when people give their time and skills to collaboratively build software. While most people wouldn't insist that their UNIX shell is licensed under the GPLv3+, it does matter and is a big PRO for Bash. See More

Haxe

Top Pro

Compiles to multiple platforms and languages

Haxe allows you to develop for Web, iOS, Android, Blackberry, Windows, OSX, Linux and others, all at once, without the need to switch languages and maintain separate code bases. This is possible because Haxe can compile to JavaScript, ActionScript, Flash AVM bytecode, C++, Neko, PHP, C# (.NET) and Java. Support for even more platforms and languages is under development. See More

Top Con

Bad support in some popular IDEs

While it has great support in Visual Studio Code and Vim for example, it still lacks support in some IDEs such as IntelliJ. See More

Top Pro

Powerfully expressive but easy to learn

The language was designed to be very expressive with the smallest possible amount of syntactic sugar. There are actually fewer keywords than other languages with similar power. See More

Top Con

You need to code interfaces to work with existing JavaScript code

Some popular libs like JQuery have maintained externs, for any specific code or lib already in JS you have to write the externs to use it in your haxe application. See More

Top Pro

Extremely fast compilation

Haxe can easily compile over 100,000 lines of code to JS in seconds on a mid-spec computer. See More

Top Con

No Qt support

There is currently no support for Qt. See More

Top Pro

Similar to JavaScript and ActionScript 3

The language is very easy to learn for those with background in JavaScript or ActionScript 3. See More

Top Con

Full programs only

You can create small utility functions with Haxe, but generally it is a lot more work than with other JS compilers. Haxe is best used when you have a larger project. See More

Top Pro

Large library support. From servers to games.

Haxelib (common library repo) and other sources contain large codebases for anything from cryptography to communications. A lot of these are fully cross platform and work with the JavaScript target. The JavaScript target can be used for everything from node.js server applications (with code completion) to games using either the Flash-like OpenFL library or direct canvas or WebGL programming. See More

Top Con

It's not easy to convince people it's as good as it really is unless you can get them to really try it

Top Pro

Established project

Haxe has been around for more than 10 years (since 2005) and whilst not the most popular project, has had continuous growth. Highly unlikely to disappear or for support to stop. See More

Top Pro

Friendly community

Friendly community See More

Top Pro

Pick up errors at compile time

One big advantage over pure javascript, (or some other languages listed here) is that Haxe will pick up a whole range of errors when you compile, saving you the pain of having to try and debug them later. This includes everything from syntax errors ("Unexpected ;") to type errors ("Class user has no field username. Suggestion: username"). See More

Top Pro

First class code completion

Code completion is built into the compiler and available to the IDE allowing for much smarter code completion that can actually parse and understand the syntax tree. See More

Top Pro

Small, readable output

The output that is generated can be trimmed using "dead code elimination" to only include those functions and libraries that are strictly necessary. All code is very readable with only minimal extras for specific functionality. Small output is good for frontend development as file size is a major concern. See More

Top Pro

Powerful type inference with strong typing

After a type is inferred from its context, it cannot be changed to a new type, and type safety is done at compile time so it stays safe without the extra maintenance required for static typing. See More

Top Pro

Syntactic macros

Syntactic macros allow you to extend compiler features at the syntax tree step. Macros come into play after code is parsed into the abstract syntax tree, and macros allow you to transform it before the rest of the compilation completes. This provides for immense power, while at the same time scoping the extensibility at a level that is powerful, but well constrained. See More

Top Pro

Code reuse server side and client side

You can use the same classes on the server as you do on the client where applicable. This saves a lot of time. See More

Top Pro

Ability to use existing JS libraries

Haxe has the ability to use "externs". These are haxe files which describe the usage of existing JS libraries. Get code completion and compile-time-checking for everything from jQuery to Node.js. Even without externs, native JS code can still be used through untyped code. See More

Top Pro

Can create complex applications without needing webpack, npm or other crutches

Haxe has the power and expression to not need the npm dependancy hell that is common in js and typescript, bit it's still simple. See More

Top Pro

Algebraic data types and pattern matching.

Top Pro

Offload execution to the server with remoting

Using a remoting proxy you can get type safe server to client communications, allowing for remote method execution on the server as if they were part of the client side code. See More

Top Pro

Package management like Java

Package tree is just directory tree, it's wonderful! See More

Top Pro

Builtin conditional compilation support

Haxe supports conditional compilation, so depending on compiler flags Haxe will include or exlcude sections of your code. Making it easy to have debug and release builds. See More

Top Pro

Abstract enums allow constants with exhaustiveness check

You can define constants in an abstract enum and when used in a switch/case statement Haxe checks for exhaustiveness, making sure every constant is covered - with no runtime implication. See More

Top Pro

Type safety for exísting JS libraries

Haxe compiler will check types when using externs for existing libraries. See More

Top Pro

Julia

Top Pro

Almost as fast as C

Julia runs almost as fast as (and in fact in some cases faster than) C code. See More

Top Con

Young language with limited support

Julia was released in 2012. Due to its short existence, there is a limited amount of support for the language. Very few libraries exist as of yet, and the community is still quite small (though growing quickly). See More

Top Pro

Great standard REPL

Out of the box Julia has a very good Read-Eval-Print-Loop, which both completes functions and types, as well as completion based on history of previous statements. It integrates well with the shell and has an excellent online help system. See More

Top Con

1-based array and column major

This design probably comes from Matlab, but makes it unnatural to interface C and C++ and python. See More

Top Pro

Nice regular syntax

Julia code is easy to read and avoid a lot of unnecessary special symbols and fluff. It uses newline to end statements and "end" to end blocks so there is no need for lots of semicolons and curly braces. It is regular in that unless it is a variable assignment, function name always comes first. No need to be confused about whether something is a method on an object or a free function. Unlike Python and Ruby, since you can annotate the types a function operates on, you can overload function names, so that you can use the same function name for many data types. So you can keep simple descriptive function names and not have to invent artificial function names to separate them from the type they operate on. See More

Top Pro

Written in itself

The Julia language is written in itself to a much larger extent than most other languages, so a budding programmer can read through the depths of the standard library and learn exactly how things work all the way down to the low-level bit-twiddling details, which can be englightening. See More

Top Pro

Amazing learning curve

Julia requires no boilerplate code – a beginner needs to write only the parts they care about. This combined with the REPL provides the best learning experience available. See More

Top Pro

High-level code

Julia provides a high level of abstraction, making platform-independent programming trivial and easing the learning curve. See More

Top Pro

Function overloading

You can have multiple functions with the same name, but doing different things depending on function arguments and argument types. See More

Top Pro

Strong dynamic typing

Dynamic and high level, but does not isolate the user from properly thinking about types. Can do explicit type signatures which is great for teaching structured thinking. See More

Top Pro

Strong Metaprogramming

Julia allows you to edit Julia code in the language itself and write powerful macros. It is a great introduction to metaprogramming features See More

Top Pro

Powerful n-dimensional arrays

Julia has built in n-dimensional arrays similar in functionality as Python's numpy. See More

Top Pro

Function and operator broadcasting

You can perform operations on scalars, for example 2^2 or [1, 2, 3].^2. See More

Go

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

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

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

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

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

Top Con

Forces K&R style and won't allow Allman style

Golang developers were extremely short-sighted and biased by forcing the K&R style, which should never have happened. Basically kicking Allman style users out of their language. See More

Top Pro

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 Con

Doesn't have true enums

Golang does weirdness with const versus having real enums, like other languages. This reflects the stubbornness and shortsightedness of the core developers, similar to the issue with generics, where it was denied that it was needed until it became too obvious that it should have been added years ago. 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 Con

Golang controlled by Google

Solves Google problems, which might not be your or the majority of user's problems. Was created for the benefit and purposes of Google, so is less flexible in language direction and options. 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 Con

Easy to shadow variable

Due to single character only difference, declare and assign statement can easily shadow variable from outer scope unconsciously. Example: err := nil if xxx { err := somefunctionthatreturnsanerr } return err // always return nil 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 its 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 Con

No forms designer

Those who are used to Visual Studio can feel the lack of a forms designer for rapid development. See More

Top Pro

Supports functional programming techniques such as function literals

This naturally also supports first class and high order functions, so you may pass functions as variables to other functions. See More

Top Con

Bizarre syntactic choices like a unique date format.

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 Con

It appears Google uses position to snuff out or suppress other languages

Newer languages that could threaten Golang (or other Google controlled languages) appear to have suppressed search results on Google and YouTube. Dangerous situation where large company can manipulate user choice and market share. The freedom to freely choose and user rights need to be protected. See More

Top Pro

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 Con

Changing visibility requires renaming all over the code

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 Con

Lacks support for immutable data

Only way to prevent something from being mutated is to make copies of it, and to be very careful to not mutate it. 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 Con

Does not have sum types

Makes it harder to have functions of different parameters types in a non OOP language. Thus messy generics and interfaces, and more confusion, where sum types could have solved a number of issues. 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

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

Top Pro

Automatically generates API documentation for installed packages

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

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

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

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

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

Clojure

Top Con

Confusing error messages

Clojure's error messages more often than not are very confusing. They usually involve stack traces that do not thoroughly explain where the error was caused or what caused it. See More

Top Pro

Immutability is the default

Clojure programmers are highly encouraged to use immutable data in their code. Therefore, most data will be immutable by default. State change is handled by functions (for transformations) and atoms (an abstraction that encapsulates the idea of some entity having an identity). See More

Top Con

Tied to the JVM and it's limitations.

Some language constructs were obviously created as workarounds for JVM limitations. This makes the language much less elegant than it could have been. Also, the JVM has a very cumbersome FFI. See More

Top Pro

Minimal syntax

Being a LISP, programs are simple: they're just functions and data. That it doesn't get bogged down with syntax or the loftier FP concepts like monads makes it one of most approachable functional languages for beginners. See More

Top Con

Syntax can be alien / jarring for those used to other Lisps

Perhaps some may consider this attribute an advantage, but I do not. Clojure does not attempt to maintain significant compatibility with other Lisps. So, if you already know a Lisp or are used to the way Lisp works in general, you'll probably be confused if you take a look at Clojure. See these resources for more details on this subject: https://clojure.org/reference/lisps http://stackoverflow.com/q/6008313/2636454 http://gilesbowkett.blogspot.com/2015/01/one-major-difference-between-clojure.html http://softwareengineering.stackexchange.com/q/153128/166211 See More

Top Pro

Tries to solve problems as simply as possible

Simplicity is one of the pillars on which Clojure is built. Clojure tries to solve many problems in software development as simply as possible. Instead of building complex interfaces, objects or factories, it uses immutability and simple data structures. See More

Top Pro

Good for writing concurrent programs

Since Clojure is designed for concurrency, it offers things like Software Transaction Memory, functional programming without side-effects and immutable data structures right out of the box. This means that the development team can focus their energies on developing features instead of concurrency details. See More

Top Pro

Huge ecosystem of libraries to work with

There's a very large ecosystem of high-quality Clojure libraries which developers can use. One example is Incanter. It's a great data analytics library and a very powerful tool for dealing with matrices, datasets and csv files. See More

Very easy to integrate with C and C++

One of the best features of Lua is its very well designed C API. This is very useful if you have an existing C library you need to integrate with Lua or quickly get a Lua script running on the C side of the game. Finally Lua plays so nice with C that if you need to optimise for speed you can re-write it in C a lot easier than other languages. See More

Top Con

Easy to make mistakes when declaring variables

When writing a function, if a programmer forgets to declare a variable, that variable will be declared at global scope. The code will seem to run fine at first, but if another function uses a variable with the same name, but fails to declare it, it will create subtle, incredibly difficult to find bugs. See More

Top Pro

Great documentation

The official Lua documentation is very helpful and thorough. There are also a large number of online resources or books with lots of helpful information for beginners and advanced users alike. See More

Top Con

Some concepts may not be applied to other "mainstream" programming languages

Lua features a prototye-based inheritance model. While this is also used by Javascript, it's not used by many other mainstream languages, and so some of the concepts learned while learning Lua won't be very applicable to other languages. Another thing that makes Lua different from other programming languages, is the fact that Arrays start at 1 instead of 0. While helpful for beginners, it can complicate logic and make it very confusing when switching languages. See More

Top Pro

Portable

Lua can be built on any platform with a ANSI C compiler. Other than that, Lua is extremely small. For example, the tarball for Lua 5.2.1 is only 245K compressed and 960K uncompressed (including documentation). When built on Linux, the Lua interpreter built with the standard libraries takes 182K and the Lua library takes 243K. The small size and the ability to build with a C compiler make Lua an extremely portable language that can run on a lot of different systems and computers. See More

Dart

Top Pro

Great async language support

Dart is a single threaded programming language. So if any piece of code blocks the execution of the program, the program practically freezes. To avoid this Dart makes use of asynchronous operations which let your program run without getting blocked. This is done through Future objects. A Future is an object which represent a means for getting a value at a certain point in the future. A function may invoke a Future and when that happens, two outcomes can be achieved: The function is unable to return a value, so it queues up work to be done and returns an uncompleted Future object. Or later when a value is available to be returned, the Future object completes with that value. See More

Top Con

Doesn’t generate consumable JavaScript at present

Dart builds to JavaScript but the entire app needs to be built to JavaScript at once for now (that may change in the future). See More

Top Pro

Great standard library

Dart includes a truly comprehensive core library, making it unnecessary to include disparate, external resources for basic functionalities Other than reducing the need to pull in various 3rd-party utilities this also ensures that all Dart code looks and feels the same. Out of the box, the developer gets core libraries to help with: async, collections, strings, regexps, conversions, formats, file I/O, math, typed data, and more. See More

Some examples of those tools include: pub - package and dependency management and build tool analyzer - static syntax analysis with linter, quick fixes, autocompletion support for easy IDE integration test - powerful and flexible testing framework and test runner dev_compiler - generate reusable JS instead of tree-shaken minified JS output (work in progress) dartfmt_ - source code formatter server-side VM observatory - a powerful tool for profiling and debugging running Dart code (for Dartium and Dart server code) See More

Transpiled JavaScript code works on all browsers

In Dart many browser differences (subtle differences and also missing features) are abstracted away or polyfilled. When Dart is transpiled to JS the output works on all supported browsers. There is usually no need to load polyfills or to consider browser differences during development. No need for libraries like jQuery to make the same code work the same on all browsers. See More

May be difficult to use some JavaScript libraries

Dart is much more than a programming language, it's a platform with its own standard libraries and tools. It's a major departure from JavaScript itself (even though it can compile to JS) that it's not possible to directly interact with JavaScript libraries in Dart. Instead, you have to use a special interop library which exposes the wrapped versions of the JavaScript objects that you are accessing. While this enables Dart to sandbox JavaScript so that its problems do not leak into a Dart application, it also means that it may be cumbersome to use libraries which don't have a wrapper library available.

Will be familiar to Java developers

The language will look familiar to Java developers, easing the learning curve. And yet, while it's similar, it has some nice syntax facilities to avoid common boilerplate code found in Java. Code is terser, yet readable. See More

Easy prototyping

Dart has an optional type system which makes Dart a great language for prototyping. It encourages developers to gradually evolve their programs without worrying about types first. See More

Can compile to efficient machine code

Dart was designed to be as expressive as possible. Ahead-of-time compilers can compile Dart code to efficient machine code. This is especially important when deploying to mobile where you don't want (or can't) use a JIT. See More

Optional strong mode.

Strong mode applies a more restrictive type system to Dart to address its unsound, surprising behavior in certain cases. See More

Support of semi-coroutines (generators)

Generators, also known as semicoroutines, are also a generalization of subroutines. Generators are primarily used to simplify the control of iteration behavior of a loop, the yield statement in a generator passes a value back to a parent routine. A generator is very similar to a function that returns an array, in that a generator has a certain number of values. But instead of building and returning an array that contains all the wanted values, a generator returns them one at a time, this saves memory and allows the caller function to start processing the first few values immediately.
