Nim (formerly named Nimrod) is an imperative, multi-paradigm, compiled programming language designed and developed by Andreas Rumpf. It is designed to be "efficient, expressive, and elegant", supporting metaprogramming, functional, message passing, procedural, and object-oriented programming styles by providing several features such as compile time code generation, algebraic data types, a foreign function interface (FFI) with C and compiling to JavaScript, C and C++..
