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
o1 = Object.create(null);
o2 = Object.create(null);
o3 = Object.create(null);
o1.a = o2.a = o3.a=1;
Object.freeze(o2);
Object.seal(o3);
Ready to run.
