CoffeeScript - 7 Reasons You Are Totally Gonna Hate It
From the CoffeeScript homepage:
CoffeeScript is a little language that compiles into JavaScript. Think of it as JavaScript’s less ostentatious kid brother – the same genes, roughly the same height, but a different sense of style. Apart from a handful of bonus goodies, statements in CoffeeScript correspond one-to-one with their equivalent in JavaScript, it’s just another way of saying it.
This 7 reasons presentation is wrapped in a nasty flash-document viewer, but shows off some nice examples of the syntax and the getting started process.
