Recently I’ve been playing with Hubot plugins code in coffeescript for our company. That’s a while I didn’t do much js but I used it for a long time and I didn’t find it too difficult to catch up. But for some reason, it brought me the same feeling I have each time I get back to that language. I feel dirty. Still I can do what I need to do, for sure, but I don’t feel like a builder, more like an acrobat. And I’m far from a purist.
