What are Angular Reactive Forms and how do Observables work with them?

Angular Reactive Forms are a way to manage form inputs in a reactive manner, allowing for dynamic form creation and validation. Observables are used to handle asynchronous data streams, making it easier to react to changes in form state.

Can you explain how to set up a simple Reactive Form?

Sure! To set up a simple Reactive Form, you need to import ReactiveFormsModule in your app module, create a FormGroup in your component, and bind it to your template using formGroup directive.

What are the benefits of using Observables with Reactive Forms?

Using Observables with Reactive Forms allows you to easily listen for changes in form values, handle validation asynchronously, and manage complex form interactions efficiently.

Can you give an example of using an Observable in a Reactive Form?

Absolutely! You can use the valueChanges property of a FormControl to subscribe to changes. For example: this.myForm.get('myControl').valueChanges.subscribe(value => { console.log(value); }); This will log the value every time it changes.
