032 RC CoffeeScript

CoffeeScript is a language written by Jeremy Ashkenas that compiles to Javascript. Its syntax is much more friendly than native JavaScript. Especially if you're used to languages like Ruby or Python. As or Rails 3.1, CoffeeScript is available by default and a coffeescript file is created in /app/assets/javascripts every time you run the scaffold generator. A few of my favorite features of the language are: I can ignore parenthesis (mostly), semi-colons, and curly braces Function notation Objects with nested notation Variable safety (not creating globals) Splats on lists Classes Always returns last expression String interpolation I don't like: Operator aliases Resources: CoffeeScript Webpage CoffeeScript Cookbook CoffeeScript Basics (video) CoffeeScript: The Cool Parts (video)
