title: Why i get wrong number of child of div with Javascript?
body: <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>var count = $("#abc").length;
  console.log('Count : ' + count)</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"&gt;&lt;/script&gt;
  &lt;div style="display:none;" id="abc"&gt;&lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>I get result = 1. Why is this? The div does not have any children? How can I fix this to get the correct number of children?</p>
