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 digits = "0123456789abcdefghijklmnopqrstuvwxyz";
var toString = function (n, radix) {
var s = "";
do {
var x = Math.floor(n / radix);
s += digits.charAt(n - radix * x);
n = x;
} while (n !== 0);
return s;
};
var v0 = 42;
var v1 = 4503599627370495;

Ready to run.
