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
var Uint32 = new Uint32Array(0x10000);
var arr = [];
for (var i = 0x10000 - 1; i >= 0; --i) {
Uint32[Math.random() * 0x10000 | 0] = (Math.random() * 0x100000000) | 0;
arr[Math.random() * 0x10000 | 0] = (Math.random() * 0x100000000) | 0;
}
var sum = 0;
Ready to run.
