I know CoffeeScript and abandoned it for the reasons I outlined above. Sure, you can compile your CS to JS. But then why not just write JavaScript?

If I were you, I wouldn't be looking forward to dealing with conflicts with keywords like `for..in`, `class`, and even `super`. But to each their own.

Why have you decided to use CoffeeScript here? To me it seems really hard to justify when features are incompatible with ECMA 6. This makes me a little nervous about relying on these lessons.
