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
const obj = Object.create(null);
const map = new Map();
const checks = [];
for (let n = 0; n < 1000; ++n) {
const entry = {value: n};
obj[n] = entry;
map.set(n, entry);
if (Math.random() < 0.5) {
checks.push(n);
}
}
Ready to run.
