jQ.Mobi VS zepto

JavaScript performance comparison

Revision 84 of this test case created by bill

Info

This is an edited test from http://jsperf.com/jqm3/26 by @DevinRhode2

I added a raw JS baseline, and another test that uses javascript prototypes to create some jquery-like abstraction, but yield nearly the same performance as raw JS. This makes one consider the Prototype javascript library. In attempting to add the Prototype version, I decided that it's too different, even as a pretty well versed javascript developer.

From: http://api.prototypejs.org/dom/Element/new/, a Prototype test case would look something like this:

var ul = new Element('ul').update("<li>Hello PrototypeJS world, you're strange.");

.update? .text or .innerText are far too commonplace, and .update truly threw me for a second. PrototypeJS is great, but I'd rather see a jQ.Mobi re-write that heavily uses prototypes of native objects. By my investigation on their docs site, prototypes don't seem modified at all. I'm curious about the feasibility of a jQ.Mobi re-write that heavily uses prototypes
