valueChanges() in angular reactive forms| Reactive forms in angular | Complete Angular Tutorial

Here, you will learn about the valueChanges() in angular reactive forms. In Angular Reactive Forms, you can detect and respond to changes in form values using the valueChanges observable.

The valueChanges observable emits an event every time the form value changes. You can subscribe to this observable to perform some action whenever the value of any form control changes.
You can use this valueChanges observable to implement different behaviors, such as validation, conditional formatting, or updating other parts of your application based on the form value changes.
