An example of an AI chatbot conversation about advanced Angular hooks and their usage.
What are advanced Angular hooks and how can I use them?
Advanced Angular hooks are lifecycle hooks that allow you to tap into key events in a component's lifecycle. They include hooks like ngOnInit, ngOnChanges, and ngOnDestroy, among others.
Can you explain how ngOnInit works?
Sure! ngOnInit is called once the component is initialized. It's a great place to perform any initialization logic, such as fetching data from a service.
What about ngOnChanges?
ngOnChanges is called whenever an input property changes. It receives a SimpleChanges object that contains the current and previous values of the changed properties.
How can I use multiple hooks together?
You can use multiple hooks in a single component to manage different aspects of its lifecycle. For example, you might use ngOnInit to fetch data and ngOnDestroy to clean up subscriptions.
