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 = 31,
b = 5;
function floor() {
return Math.floor(a / b);
}
function bitop() {
return (a / b) | 0;
}
function bitflip() {
return~~ (a / b);
}
</script>
Ready to run.
