When comparing Julia vs V, the Slant community recommends V for most people. In the question“What is the best programming language to learn first?” V is ranked 4th while Julia is ranked 12th. The most important reason people chose V is:
V is easier than C and fast like C.
Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Almost as fast as C
Julia runs almost as fast as (and in fact in some cases faster than) C code.
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.
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.
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.
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.
Pro Powerful n-dimensional arrays
Julia has built in n-dimensional arrays similar in functionality as Python's numpy.
Pro Function overloading
You can have multiple functions with the same name, but doing different things depending on function arguments and argument types.
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.
Pro High-level code
Julia provides a high level of abstraction, making platform-independent programming trivial and easing the learning curve.
Pro Function and operator broadcasting
You can perform operations on scalars, for example 2^2 or [1, 2, 3].^2.
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
Pro REPL-based
The Julia REPL allows quickly testing how some code behaves and gives access to documentation and package management immediately in the REPL.
Pro Fast like C
V is easier than C and fast like C.
Pro C Interop
Can import C libraries, structs, and headers.
Pro Cross-platform
Compile to many OSes.
Pro Simplicity
V is simple and powerful.
Pro Can create multi-OS GUIs
Multi-OS GUI creation is more integrated into the language than others.
Pro Clear syntax
Highly understandable language.
Pro Sum types
V has Sum Types.
Pro Generics
V has generics.
Pro Closures
V has closures, which gives the user additional options and usefulness.
Pro Safety
V is very safe.
Pro Single paradigm
Follows the philosophy that there should be only one way to do something, as opposed to multi-paradigm languages like C++.
Pro Supports concurrency and channels
Can run functions concurrently that communicate over channels.
Pro Fast compile times
Compiles programs fast, less waiting around, so more productive and fun.
Pro Friendly and helpful community
Just check the V Discord channel or their GitHub Discussions and you will see by yourself.
Pro Inline assembly
Can add Assembly code.
Cons
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).
Con 1-based array and column major
This design probably comes from Matlab, but makes it unnatural to interface C and C++ and python.
Con Rapid changes in a language syntax/features
Since V language under a continuous development and core syntax and features will be "frozen" in a version 1.0.0, updating from older version of a language can cause a code rewrite of previously working program.
Con V 1.0 release was planned for December 2019
The first version of the language was publicly released in June of 2019, version 0.1.x. First beta version of the language was released June of 2022, version 0.3. x. Language has progressed faster than most. Welcomes contributors to join the project.
