title: Which ES2018 features are implemented in Typescript?
body: <p>Could somebody please help me with the following question: </p>
  
  <p>Where can I find the list of ECMAScript features that have been implemented by Typescript? I'm particularly interested in <a href="http://exploringjs.com/es2018-es2019/ch_regexp-unicode-property-escapes.html" rel="nofollow noreferrer">RegExp Unicode property escapes</a> which was added in ES2018 (which happened pretty recently according to <a href="http://2ality.com/2017/02/ecmascript-2018.html" rel="nofollow noreferrer">this post</a>). I would like to use this feature to add multi-language support for <a href="https://github.com/angular/angular/pull/22600#issuecomment-371533702" rel="nofollow noreferrer">Angular</a>, but couldn't find any evidence that it was adopted by Typescript.</p>
  
  <p>P.s. I spent some time and found the following resources <a href="https://github.com/Microsoft/TypeScript/issues/20342" rel="nofollow noreferrer">Issue on github</a>, <a href="https://github.com/Microsoft/TypeScript/pull/20385" rel="nofollow noreferrer">PR on github</a>, <a href="https://github.com/Microsoft/TypeScript/wiki/Roadmap" rel="nofollow noreferrer">Typescript Roadmap</a>, <a href="http://kangax.github.io/compat-table/es2016plus/#test-RegExp_Unicode_Property_Escapes" rel="nofollow noreferrer">ES compatibility Table</a>. </p>
  
  <p>From my understanding, they are very closely related to my question, but none of them can actually confirm that Unicode property escapes was implemented. I can still fallback to the <a href="https://stackoverflow.com/a/48902765/2009145">transpiled</a> solution, but it would be nice to use <code>/\p{L}/u</code> instead of very long string.</p>
  
  <p>Thank you in advance!</p>
