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>
function getRandomInt (min, max) {
return Math.floor(Math.random() * (max - min + 1)) + min;
}
ALPHABET = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
</script>
var n = getRandomInt(0, 25);
Ready to run.
