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
<script>
function checkSum() {
let sum = 0;
for (let i = idArray.length - 1; i >= 0; i--) {
const digit = idArray[i];
const multiplier = (idArray.length - i) % 2 === 0 ? 2 : 1;
const product = digit * multiplier;
sum += product > 9 ? product - 9 : product;
}
const res = sum % 10 === 0;
const validChecksum = res;
return res;
}
Ready to run.
