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
<script>
var arr = (function() {
var arr = [],
i = 100;
while (i--) {
arr.push(Math.random());
}
return arr;
})();
var sum;
function iterate(i) {
sum += i;
}
function forEach(arr, callback, scope) {
for (var i = 0, l = arr.length; i < l; i++) {
callback.call(scope, arr[i], i, arr);
}
}
function forEach5(arr, callback, scope) {
for (var i = 0, l = arr.length; i < l; i++) {
if (i in arr) {
callback.call(scope, arr[i], i, arr);
}
}
