Prompt 4

You are building an app and have to store data about user profiles. Each user profile is represented by an Object with an id, username and password like this:

{
  id: 1234,
  username: 'SpongeBob',
  password: 'dandelion'
}

Now, imagine you had hundreds of these user profiles and you want to be able to find any one of those objects by its id or username. Would it be better to store all of those objects in an array of objects, or in an object of objects? Why?
