JavaScript template language shootoff

JavaScript performance comparison

Revision 205 of this test case created by Dave Tonge

Info

A brief comparison of some JavaScript templating engines on a short template: 6 header tags, and 10 list items.

Note: When adding a new test, please ensure that your test returns the same HTML string (or equivalent DOM fragment) as the others.
