Editor doesn't support Arrow Function class methods in JS

I have a project that I am using React in. I have it set up to use all proposed JS features (stage-0) with Babel. Everything is functional, but the editor shows an error Parsing Error: Unexpected token = when creating class methods with arrow functions.

IMO this is a low priority as it doesn’t break anything, but it would be nice to have fixed.

Hey @artjumble thanks for the request! I’ve moved it to Feature Ideas to go along with some other linting changes that we hope to work on in the future - be sure to add your vote!
