The author uses CoffeeScript for completely different reasons than I do. While a lot of the convenience features of CoffeeScript are awesome, I use CoffeeScript more to compile JS to standards-compliant, consistent code. Variables are hoisted, commas are automatically inserted, semi-colons are taken care of, and the entire script is put into a lovely self-invoking function that helps fool-proof things. Furthermore, because CoffeeScript requires (sort of) a compilation step, errors are caught and debugging becomes MUCH easier than it ever was with plain JavaScript. Most text editors now have plugins that will compile selected text to JavaScript so you can preview the end result and make sure that you're getting the output you want. The better part? When JavaScript best practices evolve, CoffeeScript can evolve with it, but the code can more-or-less stay the same. Awesome!
