title: VueJS not loading on IE11
body: <p>IE11 does not load my VueJS app.</p>
  
  <p>I currently have a console log error: <strong>SCRIPT1003: Expected ':'</strong> on the below line <em>async</em>:</p>
  
  <pre><code>   methods: {
         async getData() {
  </code></pre>
  
  <p>I have tested using a polyfill but with no improvement, what am I missing?</p>
  
  <p>Thanks</p>
