title: Javascript intellisense in ACE editor
body: <p><strong>TL;DR</strong></p>
  
  <p>I need intelligent autocompletion/intellisense for JavaScript in ACE Editor.</p>
  
  <p><strong>Explanation</strong></p>
  
  <p>I am creating an online IDE for JavaScript using ACE Editor. Is there any library or open-source project that allows intelligent autocompletion for JavaScript.</p>
  
  <p>JavaScript is a dynamic language, intellisense integration is trivial for such languages (<a href="http://www.typescriptlang.org/Playground" rel="noreferrer">TypeScript</a> does support this). ACE editor only supports basic autocompletition (like Sublime Text) using <code>enableBasicAutocompletion</code>.</p>
  
  <p>I need intelligent autocompletion, an engine that parses the javascript in backend in realtime and provides suggestions.</p>
  
  <p>Any help regarding this issue would be appreciated.</p>
  
  <p>Thanks.</p>
