{ text: "Hello there. U good?", is_user_msg: false }

Now, representing the messages field within the state with an object, we should have something like this:

messages: { user_id: { text, is_user_msg }, user_id_2: { text, is_user_msg } }

Notice how I’m also using an object instead of an array again. Also, we’re going to map each message to the unique key, user_id of the contact.

This is because a user can have different conversations with different contacts, and it is important to show this representation within the state object. For example, when a contact is clicked, we need to know which was clicked! How do we do this? Yes, with their user_id.

The representation above is incomplete but we’ve made a whole lot of progress! The messages field we’ve represented here assumes that each contact (represented by their unique user id) has only one message.

But, that’s not always the case. A user can have many messages sent back and forth within a conversation.

So how do we do this?

The easiest way is to have an array of messages, but instead, I’ll represent this with objects.
