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 arr = [],
i,
obj = Object.create(null),
key;
for(i = 0; i < 100; i = i + 1) {
var item = {index: i};
arr.push(item);
obj[i] = item;
}
var f = function(){};
f.prototype = obj;
new f;
Ready to run.
