    Communicate Between Components with Outputs & EventEmitters


    Sometimes we need to pass data from a child component to a parent component. We could pass the source down to the child as an input and modify it there, but that's not a good practice. In Angular, we can use Outputs and EventEmitters to accomplish this instead. The child component emits an event with the data that the parent listens for. The parent can then process the event data however it needs to. In this video, you'll learn how to do just that with a reactive form that needs to send its value up to its parent component.
