title: Array.prototype.slice - what if the end param is greater than the array length?
body: <p>I can't find it - what if the <code>end</code> param passed to <code>Array.prototype.slice</code> is greater than array length?</p>
  
  <p>I've tested it and it works (in Chrome), but I'm not sure if this is standard behaviour thus can be used commonly?</p>
