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
A simple Javascript benchmark comparing Number.prototype performance vs a declared function. The comparison uses a simple Javascript modulo calculation.
Number.prototype.mod = function (m) {
return ((this % m) + m) % m;
}
function mod(n, m) {
return ((n % m) + m) % m;
}
const n = 123;
Ready to run.
