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
Testing a few selectors and what is the fastest way to get them

<div id="next">
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
Ready to run.
