title: How to warn when you forget to `await` an async function in Javascript?
body: <p>I'm using Babel and Webpack. If I forget to <code>await</code> an async function, it can often go unnoticed. Once in a while, if I forgot the <code>await</code>, an error occurs in the async function and I get an <code>Unhandled promise rejection</code>. Then, I realize that I forgot the <code>await</code>.</p>
  
  <p>Is there a way to get a warning when I forget to add an <code>await</code>?</p>
