title: TypeError: undefined is not a function - .parent()
body: <p>I'm learning jquery and playing around with navigating the tree. </p>
  
  <pre><code>$('.quick-info') returns a list
  $('.quick-info')[0] grabs the first element in that list
  </code></pre>
  
  <p>When I try to find the parent of the first element in that list</p>
  
  <pre><code>$('.quick-info')[0].parent()
  </code></pre>
  
  <p>I get the error:</p>
  
  <pre><code>TypeError: undefined is not a function
  </code></pre>
  
  <p>What am I doing wrong? </p>
