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
var resultConcat = "";
var resultArray = [];
var max = 10000;
// just to be sure memory isn't an issue.
resultConcat = "";
resultArray = [];
Ready to run.
