Sorry but I have to ask about that. As you know, nowadays CoffeeScript is pretty outdated. Want to help out, create pull requests but those CoffeeScript lines makes me really sick (there is no reason to learn that in 2017) and I am quite really sure there are plenty amount of people who don't want to write CoffeeScript. So, converting the project vanilla JavaScript will increase potential contributors.
