如何通过循环关系获取所有用户

{
  "id": "user1",
  "name": "John",
  "children": [
    {
      "id": "user2",
      "name": "Alice",
      "children": [
        {
          "id": "user3",
          "name": "Bob",
          "children": []
        },
        {
          "id": "user4",
          "name": "Charlie",
          "children": []
        }
      ]
    },
    {
      "id": "user5",
      "name": "David",
      "children": []
    }
  ]
}

function getAllUsers(user, result) {
  result.push(user); // 将当前用户添加到结果列表中

  if (user.children.length > 0) {
    for (const child of user.children) {
      getAllUsers(child, result); // 递归调用，遍历子用户
    }
  }
}

const users = {
  // 用户数据结构，参考上述示例数据
};

const allUsers = [];
getAllUsers(users, allUsers); // 调用函数获取所有用户

console.log(allUsers);
