How run async / await in parallel in Javascript : <p>Finally <code>async</code>/<code>await</code> will be <a href="http://kangax.github.io/compat-table/es2016plus/#test-async_functions" rel="noreferrer">supported</a> in all major browser soon except IE.
So now we can start writing more readable code with <code>async</code>/<code>await</code> but there is a catch. A lot of people use async await like this:</p>

<pre><code>const userResponse = await fetchUserAsync();
const postsResponse = await fetchPostsAsync();
</code></pre>

<p>While this code is readable it has a problem, it runs the functions in series, it won't start fetching posts until the fetching of the user is finished. The solutions is simple, we need to fetch the resources in parallel.</p>

<p>So what I want to do is (in pseudo language): </p>

<pre><code>fn task() {
  result-1 = doAsync();
  result-2 = doAsync();
  result-n = doLongAsync();

  // handle results together
  combinedResult = handleResults(result-1, result-2);

  lastResult = handleLastResult(result-n);
}
</code></pre>
