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
function numberToString(n) {
if (n === 0)
return '0';
var arr = [];
while (n) {
arr.push(n % 10 + 48);
n = (n / 10)|0;
}
return String.fromCharCode.apply(null, arr.reverse());
}
function numberToString2(n) {
if (n === 0)
return '0';
var arr = [];
while (n) {
arr.unshift(n % 10 + 48);
n = (n / 10)|0;
}
return String.fromCharCode.apply(null, arr);
}
Ready to run.
