Question 10

@Output

Answer 10

A decorator that marks a property in a child component that allows data to travel from the child to the parent component.

The child component uses the @Output() property to raise an event to notify the parent of the change. To raise an event, an @Output() MUST have the type of EventEmitter, which is a class in @angular/core that you use to emit custom events.
