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
Please, use Javascript properties when appropriate. As you can tell they are fast. :-)
<script src="//code.jquery.com/jquery-1.6.min.js"></script>
<form>
<input type="checkbox" id="abc" />
</form>
<script>
abc = $("#abc");
</script>
Ready to run.
