Script Preparation code:

const set = new Set();
for (let i = 0; i < 10000; ++i) {
  set.add(`key_${i}`);
}
const obj = {};
for (let i = 0; i < 10000; ++i) {
  obj[`key_${i}`] = true;
}
const map = new Map();
for (let i = 0; i < 10000; ++i) {
  map.set(`key_${i}`, true);
}

Tests:

Set
let result = 0; for (let j = 0; j < 100; ++j) { const clone = new Set(set); } console.log(result);
Object
let result = 0; for (let j = 0; j < 100; ++j) { const clone = {...obj}; } console.log(result);
Map
let result = 0; for (let j = 0; j < 100; ++j) { const clone = new Map(map); } console.log(result);
