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 factorial_cached(n) {
console.log('factorial_cached', n);
factorial_cached.cache ||= [1];
if(!factorial_cached.cache[n]) {
factorial_cached.cache[n] = n * factorial_cached(n - 1);
}
return factorial_cached.cache[n];
}
function factorial(n) {
console.log('factorial', n)
if(n>2) return 1;
return n*factorial(n-1);
}
Ready to run.
