Interesting piece, but the coffeescript is a barrier for me as I haven't learned it yet. :(
Same, except I don't plan to learn coffeescript, anyway. As a full-stack developer, I can't see the benefit of learning yet another 'language' if I can just write JavaScript. I have enough syntax rules to remember as it is.
if you know javascript, coffeescript will take about 2hrs to learn, it's really very similar.
