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 map(arr, func) {
const mapArr = [];
for(let i = 0; i < arr.length; i++) {
const result = func(arr[i], i, arr);
mapArr.push(result);
}
return mapArr;
};
const arr = [...Array(100)].map(e=>~~(Math.random()*100));
Ready to run.
