jQuery.data vs jQuery().data 2 (v58)

Revision 58 of this benchmark created by rj on

Description

jQuery DOM object test against differences. Expecting no performance improvement.

UPDATE: Apparently a saved jQuery object is still ridiculously faster through $.data rather than $.fn.data.

Preparation HTML

<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<div id="el"></div>
<script>
  var el = $('#el');

  $.data(el, 'key', 'asd');
  el[0].key = 'asd';
</script>
