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
<ul>
</ul>
var ul = document.querySelector('ul');
for (var i = 0; i < 1000; i++) {
var li = document.createElement('li');
li.textContent = 'plop' + i;
ul.appendChild(li);
}
ul.textContent = '';
Ready to run.
