title: When do you choose to load your javascript at the bottom of the page instead of the top?
body: <p>I have seen JavaScript libraries being loaded at the top and bottom of the page.</p>
  
  <p>I would love to know when to make these choices. All the JavaScript code I've written all work at the top of the page, which includes jquery plugins.</p>
  
  <p>When do i load my script at any of these positions?</p>
