Node.JS -遍历对象中的数组

const data = {
  users: [
    { id: 1, name: 'Alice' },
    { id: 2, name: 'Bob' },
    { id: 3, name: 'Charlie' }
  ]
};

for (let i = 0; i < data.users.length; i++) {
  console.log(data.users[i].name);
}

data.users.forEach(user => {
  console.log(user.name);
});

const names = data.users.map(user => user.name);
console.log(names);

for (const user of data.users) {
  console.log(user.name);
}

if (data.users && data.users.length > 0) {
  for (let i = 0; i < data.users.length; i++) {
    console.log(data.users[i].name);
  }
} else {
  console.log('数组为空');
}

const updatedUsers = data.users.map(user => {
  if (user.id === 2) {
    return { ...user, name: 'Updated Bob' };
  }
  return user;
});
console.log(updatedUsers);
