An example of an AI chatbot conversation about Angular directive lifecycle hooks.
What are the lifecycle hooks in Angular directives?
In Angular, lifecycle hooks are methods that allow you to tap into key events in a directive's lifecycle, such as creation, updates, and destruction.
Can you explain the different lifecycle hooks available?
Sure! The main lifecycle hooks are ngOnInit, ngOnChanges, ngDoCheck, ngAfterContentInit, ngAfterContentChecked, ngAfterViewInit, ngAfterViewChecked, and ngOnDestroy.
What is the purpose of ngOnInit?
ngOnInit is called once the directive is initialized. It's a great place to perform any setup logic, such as fetching data.
How does ngOnChanges work?
ngOnChanges is called whenever one or more data-bound input properties change. It receives a SimpleChanges object that contains the current and previous values.
