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
Testing speed of a standard for loop vs. Array.indexOf.
<script>
var ar = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];
function indexOf (array, value) {
for (var i = 0, l = array.length; i < l; i++) {
if (array[i] === value) {
return i;
}
}
return -1;
}
</script>
Ready to run.
