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 s1 = "first";
var s2 = "second";
var comparestr = function(x, y) {var len=x.length|y.length, diff=0, i=0; while (((diff=(x.charCodeAt(i)||-1)-(y.charCodeAt(i)||-1))===0) && (i++<len)) {} return diff;}
Ready to run.
