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:
https://jsperf.app/negative-modulo/2
Selectors test of 7 useful javascript frameworks and native querySelectorAll on modern browsers.
Adding YUI3's .all() as it returns a composite object similar to something like jQuery.
Removing all but YUI, jQuery, Sizzle, and native selector engines.
