CoffeeScript is a little language that compiles into JavaScript.
Underneath that awkward Java-esque patina, JavaScript has always had
a gorgeous 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, will work in every JavaScript runtime, and tends to run as fast or faster than the equivalent handwritten JavaScript.
