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
According to https://developers.google.com/speed/docs/best-practices/rendering?hl=es-419 is more performant to do .foo than p.foo.
Let's check if this is true for jQuery's Sizzle.
<div>
<p class="foo">
Hello world
</p>
</div>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js">
</script>
Ready to run.
