title: Benefits of loading JS at the bottom as opposed to the top of the document
body: <p>What are the real benefits (if any) to loading your JS at the bottom of the document, as opposed to the top.  It seems there is a brief delay in page loading and JS dependent functionality.  </p>
  
  <p>I am using <a href="http://html5boilerplate.com">html5boilerplate</a> for beginning all my templates, but am not really sure on how beneficial loading the JS at the bottom is.</p>
  
  <p>Does it really make all that much of a difference, and if so, why?</p>
