jQuery selectors VS jQuery + Javascript native selectors (by conversion) (v380)

Revision 380 of this benchmark created by Oleg on

Description

Comparing the performance difference of varied jQuery 2.1.1 selectors. And specifficaly comparing jQuery selectors VS jQuery + Javascript selectors by conversion like $(document.getElementById("foo"));

This test page contains some dummy HTML (from html-ipsum.com) just to give the page some weight, make the selectors work a little bit.

Note that the "Tag" selector is selecting a tag that happens to be unique in the page just to be fair.
