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
Comparing the "slow loop" argument from http://www.sitepoint.com/google-closure-how-not-to-write-javascript/
<script>
var arr = [];
for (var i = 1; i <= 10000; i++) {
arr.push(i);
}
var result = -1;
</script>
Ready to run.
