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.app/negative-modulo/2 Property Getter / Setter Techniques (v7) Revision 7 of this benchmark created by Scott Wolchok on August 27, 2011 Description Testing various techniques for creating getters / setters in JavaScript. This revision uses actual prototype-based classes where possible; seems to result in a significant speedup for the method-based version.
