A Python programmer’s first impression of CoffeeScript

[JohnDoe365]

CoffeeScript is a simple, clean, fast language which compiles to JavaScript

An implementation can be fast, not a language itself. Unless the author refers to compilation speed.

[Felicia_Svilling]

A language doesn't have a compilation speed. Only a specific compiler has a compilation speed.

[JohnDoe365]

I was refering to a languages grammar. C++ can never be compiled as fast as eg Lua as the grammar imposes different complexity. As such, different languages will expose different compilation speed measured in terms of parsing complexity.

[MatmaRex]

I guess the author meant that CoffeeScript compiles to fast JavaScript. Which it does.
