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
Compare Math.pow(10, 10), 1e10, 10**10
round1 = value => {
const factor = Math.pow(10, 10);
Math.round(value * factor) / factor;
}
round2 = value => {
const factor = 10**10;
Math.round(value * factor) / factor;
}
round3 = value => {
const factor = 1e10;
Math.round(value * factor) / factor;
}
Ready to run.
