If you're considering trying Coffeescript, here are a few thoughts for you. Remember that the Vim plugin for Coffeescript compiles your Coffeescript to a js automatically every time you save, and it even shows you immediately if there are any errors. I've had difficulty setting up other Vim plugins, but this one was blessedly simple to get going.

An awesome tool for helping you to learn Coffeescript is the "Try Coffeescript" tab on http://coffeescript.org/. This lets you type a little bit of stuff, and see how it translates into Javascript, in realtime, while you type. I still use this today when I'm trying to verify I'm on the right track with a bit of punctuation (meaning, leaving punctuation out, usually).

Also, a bunch of shortcuts[0] and Syntastic (which Just Works) makes it absolutely blissful.

Note that although :CoffeeCompile operates on the whole file by default, it also works on buffer regions, so vai,c shows me the current block as JS (i is from indent-object plugin)
