--formatter breaks on common ES6 code, fixed with esformatter ^0.7.0 dep

Cross-posting here as well, not sure if that's necessary or not, but would really appreciate if this got fixed soon. It's a useful tool you created here and I'd like to be able to use from time to time the automatic formatter for converting projects with a different style.

If there's another way to help, I'd be happy to do so.
