This is what it is for me:

  Objective-C -> Nim (can compile to ObjC, calls methods directly without overhead)
  Python -> Nim (Nim is a super fast python that prevents typos)
  Ruby -> Nim (Nim is better in every-way)
  JavaScript -> Nim (compiles to plain JS (if you need talk to legacy JS libs like most people) or WASM (if you just want speed))
  C/C++ -> Nim (Can compile to C++, calls methods directly without overhead)

Basically...
