In this instance, we make use of the mergeMap often known as flatMap to map/iterate in excess of the Observable values. So within our instance when we get the homeworld, we've been finding back again an Observable inside of our character Observable stream. This makes a nested Observable within an Observable. The mergeMap operator will help us by subscribing and pulling the value out of your interior Observable and passing it back again towards the father or mother stream.
Upcoming we’ll develop a very simple course referred to as DashboardCard that’s in control of Keeping each of the Attributes you’d want the card to possess entry to after it’s dynamically established, as well as a reference towards the component that could be instantiated for the cardboard once we choose to achieve this.
