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
const haystackArray = Array.from({ length: 500 }).map((_, idx) => `item-${idx}`);
const haystackSet = new Set(haystackArray);
const assert = (val) => {
if (!val) throw new Error("assertion violated");
}
Ready to run.
