title: Advantage of *this* over event.target
body: <p>Is it better / faster inside an event listener to use <code>this</code> or <code>event.target</code></p>
  
  <p>I've been writing code like this (example is jQuery):</p>
  
  <pre><code>jQuery('input').bind('keyup', function (e) {
   var j = jQuery(e.target);
   foo(j.attr('id') , j.val() );
  });
  </code></pre>
  
  <p>And I was told to replace <code>e.target</code> with <code>this</code> because it's "better". Is there really any advantage to one or the other? </p>
  
  <p>I use target because it's a more general solution as it works for delegated events. I'm having trouble benchmarking because my tests get cluttered with the binding (Although, obviously, in this case the difference would be too small to matter anyway)</p>
