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
round1 = value => {
const factor = 1e10;
return Math.round(value*factor)/factor;
}
round2 = value => {
return Number(value.toPrecision(10));
}
round3 = value => {
return Number(value.toFixed(10));
}
round4 = value => {
return parseFloat(value.toPrecision(10));
}
Ready to run.
