title: Convert jQuery element to a regular dom element
body: <p>A regular dom element is such as:</p>
  
  <p><code>document.getElementById('a')</code></p>
  
  <p>or</p>
  
  <p><code>document.createElement('div')</code></p>
  
  <p>But jQuery returns elements in another format, so for instance I'd like to convert what is returned by <code>$('#a')</code> to the same result as what is returned by <code>document.getElementById('a')</code></p>
  
  <p>Is this possible using jQuery?</p>
  
  <p>thanks</p>
