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 a = [],
four = /four/,
b, i, pre = "test";
for (i = 0; i < 1000; i++) {
a.push(pre + i);
}
b = a.join(' ');
</script>
Ready to run.
