This is incredible. I love Python and I tried to learn JavaScript, but I had a tremendous amount of trouble with it. Moreover, I really can't stand JavaScript. CoffeeScript alleviated a lot of my concerns, but this tool is perfect considering that it lets me use a language with which I am already way more comfortable. I think that this will make an excellent learning tool for a lot of people. Thanks a lot for creating and sharing this.

This is pretty cool! It's going to get even more interesting once ES6 features are implemented :). However, i feel like javascript by itself is such a great language (has some weird parts but eh) that i would never use this. Cool project though!
