Description: A service in Angular is a class that provides specific functionality and can be injected into components, directives, or even other services. Its main goal is to encapsulate logic that can be shared across various parts of an application, thus promoting code reuse and separation of concerns. Services are fundamental in Angular’s architecture as they allow for data management, business operations, and communication with external APIs. They are created using the @Injectable() decorator, which allows Angular to recognize them as entities that can be injected into other components or services. This facilitates the implementation of design patterns like Singleton, where a single instance of the service can be shared throughout the application. Additionally, services can be configured to have different injection scopes, allowing for more precise control over their lifecycle and reach within the application. In summary, services in Angular are key components that help keep code clean, modular, and maintainable, which is essential for developing scalable and efficient applications.
