title: React suggestions and autocomplete does not work for files with js extension in VSCode
body: <p>I need to enable React related suggestions and autocomplete but in files with <code>.js</code> extension in Visual Studio Code. The only way to make it working for me is to change extension from <code>.js</code> to <code>.jsx</code>. I tried everything described in <a href="https://stackoverflow.com/questions/39320393/jsx-or-html-autocompletion-in-visual-studio-code/">this post</a> but nothing worked for me. </p>
  
  <p>Here is what I mean by React related suggestions and autocomplete.
