Why I use Coffeescript: It increases my productivity. I know Javascript, I've written a lot of Javascript, I don't need warts removed for my own protection. I write Coffeescript because it generally results in ~30% less actual code over Javascript, and the reduced boilerplate substantially reduces cognitive overhead when trying to grok a piece of code that I (or my team) wrote six months ago. I get stuff done with it, and I could get stuff done with Javascript (and often do!), but...why spend effort I don't have to in order to solve my business problems? The abrasive, condescending theme that Coffeescript is only for noobs who couldn't otherwise hack it in Javascript makes my eyes smoke from rolling so hard.
