Script Preparation code:

var fewItemSet = new Set([1, 2, 3]);
var manyItemSet = new Set(Array.from({ length: 1000 }, (_, i) => i));

Tests:

for of: few items
let result = 0; for (const item of fewItemSet) { result += item; }
for of: many items
let result = 0; for (const item of manyItemSet) { result += item; }
forEach: few items
let result = 0; fewItemSet.forEach((item) => { result += item })
forEach: many items
let result = 0; manyItemSet.forEach((item) => { result += item })
