Name: Updating complex state with this.setState()

Description: By using `this.setState()`, we can avoid needing to copy in properties we are not updating. We only need to declare the ones we are changing. ``` toggleFavorite = () => { this.setState(prevContact => ({ isFavorite: !prevContact.isFavorite })) } ```
