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
<div id="some-id">
</div>
const els = [document.body];
for (let i = 0; i < 2500; i++) {
const div = document.createElement('div');
els[Math.floor(Math.random()) * els.length].appendChild(div);
els.push(div);
}
Ready to run.
