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
Identifying the differences of CSS style selectors, which will run through Sizzle, compared to: similar selectors with a container and specific selectors like ID's.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js">

<div id="container">

</p>
<a id="single-button" class="single-button" href="#" />
</div>
cached_button = $('#single-button');
Ready to run.
