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 if you want to test the popular claim that looping backward in an array is faster than looping forward. Added a reverse while loop test as well, Looping backward is faster than forward loop and while reverse is better than all of the above.
<script>
var arr = ["a", "b", "c", "d"];
</script>
Ready to run.
