How can I optimize API calls in my Angular application?

You can optimize API calls in Angular by implementing techniques like caching, lazy loading, and using observables effectively.

What is caching and how can I implement it?

Caching stores API responses locally, reducing the need for repeated calls. You can use Angular's HttpClient with RxJS operators to cache responses.

Are there any libraries that can help with this?

Yes, libraries like NgRx Store or Akita can help manage state and cache API responses efficiently.

What about lazy loading? How does it work?

Lazy loading loads modules only when they are needed, which can reduce the initial load time and improve performance.
