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:

Check digits in a number is greater than certain threshold
function countDigitsByLog(num, threshold) {
return Math.log10(num) > threshold
}
function countDigitsByStr(num, threshold) {
return parseInt(num, 10).toString().length > threshold
}
function countDigitsByStrOpt(num, threshold) {
return `${num}`.length > threshold
}
Ready to run.
