jsPerf.app is an online JavaScript performance benchmark test runner & jsperf.com mirror. It is a complete rewrite in homage to the once excellent jsperf.com now with hopefully a more modern & maintainable codebase.
jsperf.com URLs are mirrored at the same path, e.g:
https://jsperf.com/negative-modulo/2
Can be accessed at:

A limited comparison of some popular JavaScript templating engines on a short template: 6 header tags, and 10 list items. Compared templating engines:
Same as 412 but excludes DOM node generation.
