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);

 
​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);

 
​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);

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