Why CoffeeScript?
I like CoffeeScript and significant whitespace. I'm enjoying CoffeeScript for years and it just works. But I understand that some people doubt about CS future, or simply doesn't like it. I will add gulp task to switch to plain old JavaScript soon. It will just delete *.coffee files and update .gitignore. Done. Now you have JavaScript version :-) But I would like to do more than that. Yes, ES6 is coming in town. I will add ES6 version once Closure Compiler finish its work.
