title: VSCode .hasOwnProperty() is not shown in IntelliSense
body: <p>VSCode does not show <code>hasOwnProperty()</code> in IntelliSense.</p>
  
  <p>According to this issue on GitHub this is intended. <a href="https://github.com/Microsoft/vscode/issues/54944" rel="nofollow noreferrer">https://github.com/Microsoft/vscode/issues/54944</a></p>
  
  <p>Is there a way to enable these common methods to be shown? (In JavaScript not TypeScript)</p>
