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
let vals = new Map();
function rndm() { return Math.round(Math.random()*1000);
}
function doSomething() {
let internal
internal = rndm()
return internal
}
for (let i = 0; i < 1000; i++) {
const rnd = rndm()
vals.set(`item${i}`, rnd);
}
Ready to run.
