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="foo"></div>
<script>fooEl = document.getElementById('foo');</script>
fooElC = fooEl.className = ' aaaa bbbb cccc dddd ';
fooElL = fooEl.classList;
//note the leading and trailing spaces
Ready to run.
