Step-by-step explanation:
A loading spinner in Angular is a visual indicator that shows a user that a task is in progress. It is typically used when an application is fetching data from a server or performing some other asynchronous operation. The spinner is usually displayed as a rotating icon or a set of moving dots.
For example, let's say you are building a web application with Angular that retrieves data from a remote server. When the user clicks a button to fetch the data, you can display a loading spinner to let them know that the application is working on fetching the data. Once the data is retrieved, you can hide the spinner and display the fetched data.
Overall, loading spinners in Angular are a useful UI element that provide feedback to users, indicating that their requested operation is underway.
