title: angular.element with and without `document.querySelector`
body: <p>Inside my directive I want to access a id from my DOM. I integrated jQuery in my project, But the problem is two way I can access my desired DOM:</p>
  <pre><code>var myEl = angular.element('#divID');
  </code></pre>
  <p>And</p>
  <pre><code>var myEl = angular.element(document.querySelector('#divID'));
  </code></pre>
  <p>My question is what is the difference between them?</p>
