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
Array.prototype.forE = function(fun, thisarg) {
for (var i = 0; i < this.length; i++) {
fun.call(thisarg, this[i], i, this);
}
};
var ar = [];
var total = 1000000;
for (var i = 0; i < total; i++) {
ar.push(~~ (Math.random() * total));
}
function iterator(it) {
count += it;
}
var ar = [];
Ready to run.
