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
Just a simple example showing the speed difference between populating a list with .append() & .html() innerHTML and createElement
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js">
</script>
<div id="list" style="display:none;">
</div>
var len = 200,$list=$('#list'),list=$list[0];
Ready to run.
