Where did jquery go?

by Rick Hedin

HTML

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<document html>
  <body>
    <div id="mydiv">
      Nothing to see here.  Move along.<br>
      Hm.  They both work.<br>
      In my actual code, the function defined using big arrow
      can't find jquery.
    </div>
  </body>
</document>

JavaScript

var regfcn = function () {
	var mydiv = $('#mydiv');
  console.log('In regfcn.', mydiv);
}

var arofcn = () => {
	var mydiv = $('#mydiv');
  console.log('In arofcn.', mydiv);
}

regfcn();
arofcn();
