Dev on the Code team here. Not true. Both JSX (http://i.imgur.com/01pAAsl.png & http://i.imgur.com/mRhOx8M.png) and ES6 (http://i.imgur.com/UOurihn.png) are supported in all their glory. Note that if you are editing an ES6 project, you need to create a jsconfig.json file with at least these contents, in order to let the language services know you are doing ES6:

  {
  	"compilerOptions": {
  		"target": "ES6"
  	}
  }
