Adding Objects to another object

I'm trying to add object inside an object with id as a key in react provider. Following is the use case.

const [memberList, setMemberList] = useState({
  homeTeam: [],
  awayTeam: [],
  homeTeamClone: {},
});

I can successfully add member to an array, however I'm more keen to add that in homeTeamClone object.

example of object = {"id":"3a21b0a-1223-46-5abe-67b653be5704","memberName":"Adam"}

I want final result as

homeTeamClone: {
  "3a21b0a-1223-46-5abe-67b653be5704": {"id":"3a21b0a-1223-46-5abe-67b653be5704","memberName":"Adam"},
  "3a21b0a-1223-46-5abe-67b653be5705": {"id":"3a21b0a-1223-46-5abe-67b653be5705","memberName":"Chris"},
  "3a21b0a-1223-46-5abe-67b653be5706": {"id":"3a21b0a-1223-46-5abe-67b653be5706","memberName":"Martin"},
}

I tried Object.assign(homeTeamClone, member) but did not get the expected result.

Thanks in Advance.

If the question is how to set individual member than you can do this:

const member = { id: '3a21b0a-1223-46-5abe-67b653be5704', memberName: 'Adam' };

setMemberList({
  ...memberList,
  homeTeamClone: {
    ...memberList.homeTeamClone,
    [member.id]: member,
  },
});

In this case spread all old values and add new one. (In case user with same ID is added again, object value will be from the new one)
