Dev on the Code team here. Not true. Both JSX (<a href="http:&#x2F;&#x2F;i.imgur.com&#x2F;01pAAsl.png" rel="nofollow">http:&#x2F;&#x2F;i.imgur.com&#x2F;01pAAsl.png</a> &amp; <a href="http:&#x2F;&#x2F;i.imgur.com&#x2F;mRhOx8M.png" rel="nofollow">http:&#x2F;&#x2F;i.imgur.com&#x2F;mRhOx8M.png</a>) and ES6 (<a href="http:&#x2F;&#x2F;i.imgur.com&#x2F;UOurihn.png" rel="nofollow">http:&#x2F;&#x2F;i.imgur.com&#x2F;UOurihn.png</a>) 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:<p><pre><code>  {
  	&quot;compilerOptions&quot;: {
  		&quot;target&quot;: &quot;ES6&quot;
  	}
  }</code></pre>
