How can I locate a specific value in a collection of objects?

Question

I have a firestore collection which is an object that contains other objects. I want to search this larger object based on an ID. The object looks like this:

{
  id1: {name: 'a', somethingElse: 'a'},
  id2: {name: 'b', somethingElse: 'b'},
  id3: {name: 'c', somethingElse: 'c'},

}

Since it isn't an array, and I am unable to use .find(). How can I search the object using the id, and return the name?

This is what I'm working with so far:

  function findUser(id, users){
         users.find(function(id{
          return id.name
         })
        }

which, of course, doesn't work

You can directly access objects inside another object by id:

obj[id]

let store = {
  id1: {name: 'a', somethingElse: 'a'},
  id2: {name: 'b', somethingElse: 'b'},
  id3: {name: 'c', somethingElse: 'c'},
}

function findUser(id, users){
  return users[id].name;
}

console.log(findUser('id2', store));
