In the previous lesson, we were able to introduce the concept of View Models to display information inside of our cards. Now that we have that bit of plumbing implemented, let's now introduce another model object in our application that we would like to show inside of a card: <b>Advertiser</b>. This advertiser model will have its own unique properties, sharing very little similarities with a User model object. Utilizing the middle layer of <b>CardViewModel</b> we can quickly implement a different card by applying a toCardViewModel function on advertiser.
