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 palindromeReverse(input) {
return input == input.split("").reverse().join("");
}
function palindromeChars(input){
let i = 0, j = input.length - 1;
while (i < j) {
if (input.charAt(i) != input.charAt(j)) {
return false;
}
i++; j--;
}
return true;
}
Ready to run.
