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
Make sure accesses aren't optimised out and the objects don't share the same V8 class.

var o1 = { a: 1, b: 2, c: 3 }, o2 = { d: 1, e: 2, f: 3 };
Object.freeze(o2);
var c = 0;
Ready to run.
