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 testObj = {id: 123};
const arr = Array(10000).fill(true).map(() => ({id: Math.floor(Math.random() * 100000)}))
const map = new Map();
arr.forEach(obj => map.set(obj.id, obj))
const arrWorst = [...arr, testObj]
const arrBest = [testObj, ...arr]
map.set(testObj.id, testObj);
Ready to run.
