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
window.performance.now
vs. Date.now
<script type="text/javascript">
var perf = window.performance;
var perfNow = function () {
return perf.now();
};
var date = window.Date;
var dateNow = function () {
return date.now();
};
</script>
Ready to run.
