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
Best way of running through an array of values and clearing the array (e.g. a callback queue)
<script>
var arr1 = [],
arr2, arr3, arr4;
for (var i = 0; i < 1000; i++) {
arr1.push(i);
}
arr2 = arr1.slice();
arr3 = arr1.slice();
arr4 = arr1.slice();
</script>
Ready to run.
