Using maps instead of objects

const nums = {
  1: 1,
  true: true
};

// const map1 = new Map([
//   [1, 1],
//   [true, true]  
// ]);

// map1.set('key', 'value');

// map1.forEach((value, key) => {
//   console.log(key, value);  
// });

const user1 = { name: "john" }
const user2 = { name: "mary" }

const secretKey1 = "asldjfalskdjf";
const secretKey2 = "alksdjfakjsdf";

const secretKeyMap = new WeakMap([
  [user1, secretKey1],
  [user2, secretKey2]  
]);

const key = secretKeyMap.get(user1);
console.log(key);

const user = {
  name: "john",
  verified: true  
};

const userMap = new Map([
  ["name", "john"],
  ["verified", true]  
]);

console.log(userMap.size);
