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 items = [1,2,3,4,5,6,7];
window.cachedSet = new Set([1,2,3,4]);
function getRandomItem() {
return items[Math.floor(Math.random()*items.length)];
}
Ready to run.
