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
Compare Array vs Float32Array creation
for (let i = 0; i < 1_000_000; i++) {
const a = new Float32Array(2);
const b = [0, 0];
const c = {x: 0, y: 0};
}
Ready to run.
