title: How to convert Map keys to array?
body: <p>Lets say I have the following map:</p>
  <pre><code>let myMap = new Map().set('a', 1).set('b', 2);
  </code></pre>
  <p>And I want to obtain <code>['a', 'b']</code> based on the above. My current solution seems so long and horrible.</p>
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>let myMap = new Map().set('a', 1).set('b', 2);
  let keys = [];
  for (let key of myMap)
    keys.push(key);
  console.log(keys);</code></pre>
  </div>
  </div>
  </p>
  <p>There must be a better way, no?</p>
