An example of an AI chatbot conversation about Angular component lifecycle hooks and their usage.
What are some examples of Angular component lifecycle hooks?
Angular component lifecycle hooks are methods that allow you to tap into key events in a component's lifecycle. Examples include ngOnInit, ngOnChanges, and ngOnDestroy.
Can you explain what ngOnInit does?
ngOnInit is a lifecycle hook that is called after Angular has initialized all data-bound properties of a component. It's a great place to perform component initialization.
What about ngOnDestroy?
ngOnDestroy is called just before Angular destroys the component. It's used for cleanup, like unsubscribing from observables or detaching event handlers.
Are there any other hooks I should know about?
Yes, there are several others like ngOnChanges, ngDoCheck, and ngAfterViewInit, each serving different purposes in the component lifecycle.
