How to avoid multiple API calls in Angular 16?

In today's Angular tutorial, I optimized API calls to avoid slowdowns and improve app responsiveness. By using Angular's powerful RxJS library and practical coding strategies, I was able to handle excessive API calls. I demonstrated how to create a new Angular project and connect it to Json placeholder for testing purposes. By implementing debouncing, distinct until changed, switch map, and caching, I significantly reduced the number of API calls and improved the speed and scalability of the app. These techniques ensure a smoother and faster user experience.
