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 sumDigitsInt = int => {
let sum = 0;
while (int) {
sum += int % 10;
int = Math.floor(int / 10);
}
return sum;
};
const sumDigitsStr = str => {
let sum = 0;
for (s of str) {
sum += Number.parseInt(s, 10);
}
return sum;
}
Ready to run.
