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
var n = 100;
var a = new Array(n);
var b = new Array(n);
for (var i = 0; i < n; i++) a[i] = i; b[n-i-1] = i;
Ready to run.
