如何从对象中的对象数组更新对象？

let data = {
  users: [
    { id: 1, name: 'Alice', age: 25 },
    { id: 2, name: 'Bob', age: 30 }
  ]
};

// 更新id为1的用户年龄
data.users = data.users.map(user => 
  user.id === 1 ? { ...user, age: 26 } : user
);

console.log(data);

let data = {
  users: [
    { id: 1, name: 'Alice', age: 25 },
    { id: 2, name: 'Bob', age: 30 }
  ]
};

data.users.forEach(user => {
  if (user.id === 1) {
    user.age = 26;
  }
});

console.log(data);

let data = {
  users: [
    { id: 1, name: 'Alice', age: 25 },
    { id: 2, name: 'Bob', age: 30 }
  ]
};

let index = data.users.findIndex(user => user.id === 1);
if (index !== -1) {
  data.users.splice(index, 1, { ...data.users[index], age: 26 });
}

console.log(data);
