What are the best practices for managing Angular component lifecycle?

Managing Angular component lifecycle effectively involves understanding hooks like ngOnInit, ngOnChanges, and ngOnDestroy. It's crucial to use these hooks to handle initialization, respond to input changes, and clean up resources.

Can you explain the ngOnInit lifecycle hook?

Sure! The ngOnInit hook is called once the component is initialized. It's a great place to perform component initialization, such as fetching data from a service.

What should I avoid doing in the ngOnDestroy hook?

In ngOnDestroy, avoid performing heavy computations or making HTTP requests. Instead, use it for cleanup tasks like unsubscribing from observables to prevent memory leaks.

How can I optimize performance during the lifecycle?

To optimize performance, minimize the use of change detection, use OnPush strategy, and avoid complex logic in lifecycle hooks. Also, consider using trackBy in ngFor.
