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="container"></div>
document.getElementById('container').innerHTML = '<div id="box"></div>';
var box = document.getElementById('box');
box.innerHTML = '<span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span><span>Abc123</span>';
