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
let count = 1_000_000;
let a = [];
let b = new Int32Array(count * 2);
for (let i = 0; i < count; i++) {
a.push({x: 11 * i, y: i / 6});
}
for (let i = 0; i < b.length; i += 2) {
b[i] = 11 * i;
b[i + 1] = i / 6;
}
Ready to run.
