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
function randomString() {
return Math.random().toString(36).substr(2, 5);
}
var string1 = randomString();
var string2 = randomString();
var string3 = randomString();
Ready to run.
