jQuery.data vs jQuery().data 2 (v66)

Revision 66 of this benchmark created 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.

<div id="el">value</div>
<script>
  var el = $('#el');
</script>
