Answer 1

The ngOnChanges method in Angular is invoked every time there is a change in an input property.

Step-by-step explanation:

The ngOnChanges method in Angular is invoked every time there is a change in an input property. This means that whenever there is a change in the values of the input properties of a component, the ngOnChanges method will be triggered. It allows you to perform certain actions or update the component's state based on the new values.
