CoffeeScript is a little language that compiles into JavaScript.
Underneath all those awkward braces and semicolons, JavaScript has
always had a gorgeous object model at its heart. CoffeeScript is an
attempt to expose the good parts of JavaScript in a simple way.
The golden rule of CoffeeScript is: "It's just JavaScript". The code
compiles one-to-one into the equivalent JS, and there is no
interpretation at runtime. You can use any existing JavaScript library
seamlessly from CoffeeScript (and vice-versa). The compiled output is
readable and pretty-printed, passes through JavaScript Lint without
warnings, will work in every JavaScript implementation, and tends to run
as fast or faster than the equivalent handwritten JavaScript.
