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 = []
for (let i = 0; i < 10_000; i++) {
A.push({ i })
}
function fi(a, pred) {
return a.findIndex(pred)
}
function manual(a, pred) {
for (let i = 0; i < a.length; i++) {
if (pred(a[i])) return i
}
}
function iter(a, pred) {
for (const [i, o] of a.entries()) {
if (pred(o)) return i
}
}
Ready to run.
