Script Preparation code:
const arr = []; const obj = {}; const elementsCount = 3; for (let i = 0; i < elementsCount; i++) { const s = new String(i); arr.push(s); obj[s] = true; }; const set = new Set(arr); Object.freeze(obj);
Tests:
array.includes
for (let i = 0; i < elementsCount; i++) { arr.includes(arr[i]); };
set.has
for (let i = 0; i < elementsCount; i++) { set.has(arr[i]); };
Object.hasOwn
for (let i = 0; i < elementsCount; i++) { Object.hasOwn(obj, arr[i]); };
