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 i, values = [],
sum = 0;
for (i = 0; i < 10000; i++) {

var obj = {

};
function forIdx(arr,callback){
var len = arr.length;
for (i = 0; i < len; i++) {
callback(i,arr[i]);
}
}
function forIdx2(arr,callback,thisArg){
var len = arr.length;
for (i = 0; i < len; i++) {
callback.call(thisArg, i,arr[i]);
}
}
