What is the difference between Input and Output in Angular?

In Angular, @Input allows data to flow from a parent component to a child component, while @Output allows a child component to emit events to the parent.

Can you give me an example of how to use @Input?

Sure! You can define an @Input property in the child component like this: @Input() myProperty: string; Then, in the parent component's template, you can bind to it: <child-component [myProperty]="parentValue"></child-component>.

And how do I use @Output?

You can use @Output to create an EventEmitter in the child component. For example: @Output() myEvent = new EventEmitter<string>(); Then, you can emit an event like this: this.myEvent.emit('some data'); In the parent, you can listen to it: <child-component (myEvent)="handleEvent($event)"></child-component>.

What are some common use cases for Input and Output?

Common use cases include passing configuration data to child components via @Input and notifying parent components of user actions or changes via @Output.
