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
Tests if it’s faster to remove list elements starting at the top or at the bottom.
<ul id="myul"><li>x</li></ul>
var ul = document.getElementById('myul'),
li = document.createElement('li'),
count = this.count;
ul.innerHTML = '';
li.innerHTML = 'x';
while (count--) {
ul.appendChild(li.cloneNode(true));
}
Ready to run.
