    <p>We're using hashHistory--it manages the routing history with the hash
    portion of the url. It's got that extra junk to shim some behavior the
    browser has natively when using real urls. We'll change this to use
    real urls later and lose the junk, but for now, this works great
    because it doesn't require any server-side configuration</p>

  <p>Can someone please explain what this means ?</p>
  
  <p>Is this something a begginner should understand ? (This seems to be a beginner tutorial.)</p>
