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
const len = 10;
const arr = [...Array(len).keys()];
const arr1 = arr.map(i => () => {});
const arr2 = arr.slice(0, -1).map(i => () => {});
arr2.push(() => {});
const arr3 = [];
for (let i = 0; i< arr.length; i++) {
arr3[i] = () => {};
}
const arr4 = [];
for (let i = 0; i< arr.length - 1; i++) {
arr4[i] = () => {};
}
arr4.push(() => {});
const iterate = (arr) => {
for (let i = 0; i < arr.length; i++) {
r = arr[i];
}
}
Ready to run.
