I like coffeescript. Lots of web devs that write ruby all day like coffeescript. tbh I think coffeescript is worth it just to never have to write "function(){..." or "this." again. It's also worth it for its free OOP features. It will have quirks, like what you see here, but I have hit these pain points and still love it.

I like CoffeeScript a lot actually. It seems to me that in some circumstances JavaScript is a new assembly language. Just because it is the native language of the runtime environment doesn't mean that it is the best tool for a programmer who is working to solve a particular, complex problem using it.
