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 a = {};
for (let i = 0; i < 100; i++) {
a[i] = i;
}
const b = {}
for (let j = 200; j < 210; j++) {
b[j] = j;
}
a.__proto__ = b;Ready to run.
| Test | Ops/sec | |
