// 1. Create user address
const address = new UserAddress({

  postCode: "10001",

// 2. Create user rights using factory
const rights = UserRights.fromJSON({

// 3. Create user with complex data
const user = new User({
  id: "user-123",

  createdAt: new Date(),
  photo: Buffer.from("example-image-data", "utf8"),

// 4. Serialize to JSON
const jsonData = user.toJSON();
console.log("\n📄 Serialized to JSON:");
console.log(JSON.stringify(jsonData, null, 2));

// 5. Deserialize from JSON
const userFromJson = User.fromJSON(jsonData);
console.log("\n♻️  Deserialized from JSON:");
console.log("📧 Email:", userFromJson.email);
console.log("📅 Created:", userFromJson.createdAt.toISOString());

// 6. Copy object
