title: Javascript - inline vs external script - what's the difference?
body: <p>I have a few snippets of javascript scattered about my pages - many are contained in my own .js files, however some of the stuff that I've found online sits directly on the page.</p>
  
  <p>I'm not too familiar with how javascript interacts with a page - is there a difference between adding the script inline or adding a reference to the external file?</p>
