title: Is `async/await` available in Vue.js `mounted`?
body: <p>I'd like to do something like this in <code>mounted() {}</code>:</p>
  
  <pre><code>await fetchData1();
  await fetchData2UsingData1();
  doSomethingUsingData1And2();
  </code></pre>
  
  <p>So I wonder if this works:</p>
  
  <pre><code>async mounted() {
      await fetchData1();
      await fetchData2UsingData1();
      doSomethingUsingData1And2();
  },
  </code></pre>
  
  <p>In my environment it raises no errors, and seems to work well.
  But in this issue, <code>async/await</code> in lifecycle hooks is not implemented.</p>

  <p>I could not find further information, but is it available in fact?</p>
