title: Arrow function within jQuery map
body: <p>I'm trying to use an arrow function within jQuery's <code>map</code> function. With the following titlesText is the correct length but each string is empty:</p>
  <pre><code>let titles = $(panelBody).find('h4');
  let titlesText = $(titles).map(title =&gt; $(title).text());
  </code></pre>
  <p>My ES6 transpiling is working, and jQuery is working. Any ideas?</p>
