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.

var ar = dataSet.data.is.i;
var ar2 = dataSet2.data.is.i;
var toSearch = '|15711|';
var toSearch2 = '|168312|';
var searchLen = toSearch.length;
var searchLen2 = toSearch2.length;
var results = [];</script>
Ready to run.
