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 forEach vs for in
<script src="http://underscorejs.org/underscore-min.js"></script>
var arr = [];
for (var i = 0; i < 100000; i++) {
arr.push(i)
}
Ready to run.
