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 getRandomNumber(max, min) {
max = max ?? Number.MAX_VALUE;
min = min ?? 0;
return min + Math.round(Math.random() * (max - min));
}
const data = Array(10000).fill(0).map(p => getRandomNumber());
const data2 = {};
for (let i = 0; i < data.length; i++) {
data2[data[i]] = true;
}
Ready to run.
