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
Test loop unrolling techniques, such as Duff's Device implemented in JavaScript for a function to find the max value of an array.
<script>
var data = (function() {
var arr = [],
i;
for (i = 0; i < 10000; i += 1) {
arr.push(Math.random());
}
return arr;
}());
</script>
Ready to run.
