我有以下类型的数组，其中包含我想分组的对象（复制为JSON）：

[
  {
    "name": "john",
    "lastName": "doe",
    "gender": "male"
  },
  {
    "name": "jane",
    "lastName": "doe",
    "gender": "female"
  },
  {
    "name": "peter",
    "lastName": "dickons",
    "gender": "male"
  },
  {
    "name": "eva",
    "lastName": "dickons",
    "gender": "female"
  },
]

如果我想按姓氏对每个人进行分组，我可以使用以下代码：

const groupByObjectKey = (users: User[], key: string): any => {
    return users.reduce((rv: any, x: any) => {
        (rv[x[key]] = rv[x[key]] || []).push(x);

        return rv;
    }, {});
};

const usersGroupedByLastName = groupByObjectKey(
    users,
    "lastName"
);

我现在怎么能做同样的事情，但使用相同的函数，并向它传递两个键，然后不仅按lastName，而且按性别对对象进行分组？

const groupByObjectKey = (users, key) => {
  return users.reduce((rv, x) => {
    (rv[x[key]] = rv[x[key]] || []).push(x);

    return rv;
  }, {});
};

let users = [{
    "name": "john",
    "lastName": "doe",
    "gender": "male"
  },
  {
    "name": "jane",
    "lastName": "doe",
    "gender": "female"
  },
  {
    "name": "peter",
    "lastName": "dickons",
    "gender": "male"
  },
  {
    "name": "eva",
    "lastName": "dickons",
    "gender": "female"
  },
];

const usersGroupedByLastName = groupByObjectKey(
  users,
  "lastName"
);

console.log(usersGroupedByLastName);
