Mad respect for you Dom, but why would going from Nim -> JS be Transpiling and Nim-> C++ be compiling? Both go from a high level Lang to another high level Lang.

I don't consider C/C++ high-level.

I would normally agree with you, but that seems subjective.

It is indeed a little subjective and changes with time. This Wikipedia article explains it fairly well I think: https://en.wikipedia.org/wiki/High-level_programming_languag...

I would say compiles is a more general form of transpiles. Transpiling meaning it compiles into a higher level form i.e. c, C++, JavaScript, and compile meaning it compiles into a more lower level form i.e assembly, bytecode, etc?

That's just how I look at it anyway.
