jQuery encode string to html entities

<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>

<pre id="log"></pre>

<script type="text/javascript">
var str = '<span>hello world</span>';
var encoded = $("<div/>").text(str).html();
console.log("str: " + str);
console.log("encoded: " + encoded);
$("#log").text("str: " + str + "\n" + "encoded: " + encoded);

The console outcome from above is:
