When comparing Nim vs V, the Slant community recommends Nim for most people. In the question“What are the best languages to learn for someone coming from Python?” Nim is ranked 1st while V is ranked 8th. The most important reason people chose Nim is:
There are generics, templates, macros in Nim. They can allow you to write new DSL for your application, or avoid all boilerplate stuff.
Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Great metaprogramming features
There are generics, templates, macros in Nim. They can allow you to write new DSL for your application, or avoid all boilerplate stuff.
Pro Strict typing
Checks your code at compile time.
Pro Has built-in unittest module
With built-in "unittest" module you can create test with a very readable code.
Pro Has built-in async support
Nim has "asyncdispatch" module, which allows you to write async applications.
Pro Compile-time execution
Nim has a built-in VM, which executes macros and some other code at compile time. For example, you can check if you're on Windows, and Nim will generate code only for it.
Pro Really cross-platform
The same code can be used for web, server, desktop and mobile.
Pro Easy to read
Nim has a lot of common with Python in terms of syntax. Indentation-based syntax, for/while loops.
Pro Multi paradigm
Imperative, OOP, functional programming in one language.
Pro Easy to integrate with another languages
You can use Nim with any language that can be interfaced with C. There's a tool which helps you to create new C and C++ bindings for Nim - c2nim.
Also, you can use Nim with Objective C or even JavaScript (if you're compiling for these backends).
Pro Garbage-collected
You don't need to deal with all those manual memory allocations, Nim can take care of it. But also you can use another GC, or tweak it for your real-time application or a game.
Pro Type interferencing
You only need to specify types in your procedures and objects - you don't need to specify type when you're creating a new variable (unless you're creating it without initialization).
Pro Built-in Unicode support
You can use unicode names for variables, there is "unicode" module for operations with unicode.
Pro Supports UFCS (Unified Function Call Syntax)
writeLine(stdout, "hello") can be written as stdout.writeLine("hello")
proc add(a: int): int = a + 5 can be used like 6.add.echo or 6.add().echo()
Pro Cross-platform
Compile app to run on different OSes.
Pro Sum types
V has sum types.
Pro GUI support
V comes with (simple) GUI support out of the box.
Pro Clear syntax
Highly understandable language.
Pro Safety
V is very safe.
Pro Fast like C
V is easier than C and fast like C.
Pro Closures
V has closures, which gives the user additional options and usefulness.
Pro Generics
V has generics.
Pro Supports concurrency and channels
Can run functions concurrently that communicate over channels.
Pro C Interop
Can import C libraries, structs, and headers.
Pro Fast compile times
Compiles programs fast, less waiting around, so more productive and fun.
Pro Lambdas
Supports using lambdas, which helps write more concise code without having to use so many lines.
