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
Tests to determine which function is faster for detecting whether a string matches a regex pattern.
var abcRegex = /abc/;
String.prototype.test = function(re){ return re.test(this); };
String.prototype.test2 = function(re){ return this.search(re)>=0; };
Ready to run.
