JavaScript sucks, even if Brendan Eich says it’s good enough (unbiased? lol). Its syntax is hateful, and CoffeeScript (CS from now on) came to solve this (among other problems). I have to write JavaScript in a regular basis, and learning CS seemed a good shot to make it more pleasant. I picked up The Little Book on CoffeeScript, written by Alex MacCaw, and it was a great source of information for a beginner like me. The book talks about the basic CS syntax, and it’s full of good code examples. It’s short, concise and perfect for people that want learn CoffeeScript basics.
