An example of an AI chatbot conversation about Angular lifecycle hooks usage.
What are Angular lifecycle hooks and how do I use them?
Angular lifecycle hooks are methods that allow you to tap into key events in a component's lifecycle. They help manage the component's behavior during its creation, update, and destruction phases.
Can you give me examples of some common lifecycle hooks?
Sure! Some common lifecycle hooks include ngOnInit, ngOnChanges, ngOnDestroy, and ngAfterViewInit. Each serves a specific purpose in managing component behavior.
How do I implement ngOnInit in my component?
To implement ngOnInit, you need to import OnInit from '@angular/core' and then define the ngOnInit method in your component class. This method will be called once the component is initialized.
What is the difference between ngOnInit and ngOnChanges?
ngOnInit is called once after the component is initialized, while ngOnChanges is called whenever any data-bound input properties change.
