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 jsSquare(number) {
let result = 1;
let base = number;
let exponent = 2; // Squaring, so the exponent is 2
while (exponent > 0) {
if (exponent & 1) {
result *= base;
}
base *= base;
exponent >>= 1; // Right shift the exponent to process the next bit
}
return result;
}
Ready to run.
