What are some effective data fetching techniques in Angular?

In Angular, you can use HttpClient for API calls, Observables for handling asynchronous data, and services to manage data fetching.

Can you explain how to use HttpClient for making GET requests?

Sure! You can inject HttpClient into your service and use the get() method to fetch data from an API. For example: this.http.get('api/url').
