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 literals, values = [], objects = [];
for(var i = 0; i < 1000; i++) {
var s = Math.random().toString().substring(0, 10);
values.push(s.valueOf());
objects.push(s);
}
literals = (new Function('return [\'' + objects.join('\',\'') + '\']'))();
String.prototype.work = function() {
return this.charAt(2);
}
delete String.prototype.work;
Ready to run.
