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
Checking performance of Array.reverse() vs a quick while loop.
<script>
var ar = ['a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p'];
var len = ar.length;
var backwardI = len - 1;
var forwardI = 0;
</script>
Ready to run.
