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 a = Array(6000);
a.fill(1);
const o = a.reduce((acc, v, i) => {
acc[`${i}`] = i;
return acc;
}, {})
function hasObjectMoreThanNProperties(o, n) {
let count = 0;
for (const _ in o) {
count += 1;
if (count > n) {
return true;
}
}
return false;
}
Ready to run.
