Why they are needed: - To **move repetitive code** out of components (requests, calculations, data processing). - To **organize shared data**, for example storing state, a cache, or the current user. - To **communicate with the server** (HTTP requests, an API). - To **separate responsibilities**: the component handles the UI, the service handles the logic. Services are registered in the DI system, and Angular creates and injects instances wherever they are needed.For the reviewerNote to the moderator (optional)Visible only to the moderator.
