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
<script>
var arr = ["a", "b", "c", "d"];
var big = ["a", "b", "c", "d"];
var i=5;
while (i-- > 0) {
big = big.concat(big);
}
</script>
Ready to run.
