ValueChanges in Angular Forms

The ValueChanges is an event raised by the Angular forms whenever the value of the FormControl, FormGroup or FormArray changes. It returns an observable so that you can subscribe to it. The observable gets the latest value of the control. It allows us to track changes made to the value in real-time and respond to it. For example, we can use it to validate the value, calculate the computed fields, etc.
