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>
// prepare array
var len = 1000;
var oldData = new Array(len);
for (var i = 0; i < len; i++) {
oldData[i] = [Math.round(Math.random() * 1000), Math.round(Math.random() * 1000)];
}
</script>
Ready to run.
