About Nim

proc helloWorld*(name = "World"): string =
  "Hello, " & name & "!"

let greeting = helloWorld("Exercism")
echo greeting

Nim is a general-purpose language designed and developed by Andreas Rumpf and first appearing in 2008. Designed to be efficient, expressive, and elegant. Nim is statically typed and compiled but lets you write elegant code that runs efficiently. Nim lets you target many platforms by compiling code to C, C++, JavaScript, or Objective-C. Nim syntax is similar to Python and shares many of Python's characteristics but draws inspiration from a number of languages, such as C, C++, C#, Lisp, Ada, Go, Oberon, and others.

As Nim is a general-purpose language it can be used in various places but has been filling a real niche in the area of Game development and Systems Programming including Embedded systems.

Nim gives you a lot of the convenience you find in Python and other languages, like easy to read syntax, a package management system for using new libraries in your projects, and user-friendly tracebacks for debugging errors.

Nim gives you the speed and portability of C, but with a high-performance garbage-collector and elegant syntax that makes the language very approachable to new people. Nim also gives you control, letting you change the garbage-collector or turn it off completely giving you the option to manage memory yourself. You have a variety of programming paradigms and abstraction layers with Nim.

Exercism is a great website

What I like about it is that I am able to solve the challenges in a TDD way working in a environment that I am familiar (my own PC not a browser IDE) and the cherry on the top of the cake is that I have access to code reviews.

Relaxed. Encouraging. Supportive.

I'm a student who loves to use Nim. It is a very unique and powerful language which has a lot of features. Sometimes you can even forget that you're writing in a compiled language!
