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 high = Math.pow(2,50);
var rx = /^10*$/;
function isPow2rx(x){return (rx.test(x.toString(2)));}
function isPow2bi(x){return !(x&x-1) && x>0}
</script>
Ready to run.
