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 arr = [], str;
for (var i=0; i < 100; i++) arr.push(i);
str = arr.join(' ');
var regex1 = /(^|\s)1(\s|$)/;
var regex50 = /(^|\s)50(\s|$)/;
var regex99 = /(^|\s)99(\s|$)/;
Ready to run.
