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:

function getRangeArrayFrom(startFrom, until) {
return Array.from({ length: until + 1 - startFrom }, (_, k) => k + startFrom);
}
function rangeKeysSpread(startFrom, until) {
return [...Array(until - startFrom + 1).keys()].map(i => i + startFrom);
}
function loop (startFrom, until) {
const result = [];
for (let i = startFrom; i <= until; i++) {
result.push(i);
}
return result;
}
Ready to run.
