How can I set a particular userId inside my users object on click

Question

I am mocking a userId which should be saved inside the users object of the reactions object when a certain icon is clicked inside my react component.

Below is a function updateUploadReaction that is supposed to do that for me. So, when the icon is clicked and a particular userId does not exist, it sets it inside the user object and adds 1, on clicking again it sets it to false and subtracts 1. So far, this is what I have, I need a guide on exactly how to do that.

reaction object

{

        reactions: {
            dislike: {
                count: 0,
                users: {},
            },
            like: {
                count: 0,
                users: {},
            },
            maybe: {
                count: 0,
                users: {},
            },
        },

}

function


function updateUploadReaction(id, type, uploads) {
    const updatedUploads = new Map([...uploads.entries()]);
    const upload = updatedUploads.get(id);
    const userId = uuid();

    uploads.forEach(() => {
        if (//check if userId exists) {
            upload.reactions[type].count += 1;
            upload.reactions[type].users.(// user Id value) = true;
        } else {
            upload.reactions[type].count -= 1;
            upload.reactions[type].users.(// user Id value) = false;
        }
    });

    updatedUploads.set(id, upload);

    return updatedUploads;
}

it could be single or multiple, ie as many users as have reacted. At this particular instant just one user — Ada, May 17 '19 at 11:51

Any particular reason you can't do it the same way you do it with type using the [] syntax?

.users[userId] = true

But what if she want only object of users? – ravibagul91 May 17 '19 at 11:51
According to the comment placed inside the code it looks like they want a key-value system where they can set certain userId's to true or false. – ApplePearPerson May 17 '19 at 12:00
This keeps adding 3 now when I click the icon. – Ada May 17 '19 at 12:11
