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 a = 12;
var b = 34.5;
var c = Infinity;
var typeOf = (function (toString, regExp) {
return function(obj) {
return toString.call(obj).match(regExp)[1].toLowerCase();
};
}(Object.prototype.toString, /\[object (\w+)\]/));
Ready to run.
