Description: The injectable decorator in Angular is a fundamental tool that marks a class as available for dependency injection. This means that Angular can manage the creation and lifecycle of that class, facilitating its use in other components or services. By applying the `@Injectable()` decorator, it indicates that the class can receive instances of other classes through its constructor, promoting code reuse and separation of concerns. This pattern is essential in modern application architectures, as it allows developers to build modular and scalable applications. Additionally, the decorator can receive a configuration object that defines the injection scope, providing flexibility in dependency management. In summary, the injectable decorator is a key feature that enhances dependency injection in Angular, improving code organization and maintainability.
