Description: Service injection is a fundamental concept in modern programming frameworks that allows services to be injected into components or other services. This design pattern promotes separation of concerns and code reuse, facilitating dependency management in complex applications. Services are classes that encapsulate business logic, data access, or functionalities that can be shared across different parts of the application. Service injection allows components to request these services without needing to manually create instances, simplifying the development process and improving code maintainability. Additionally, contemporary frameworks use dependency injection containers that handle the creation and lifecycle management of services, ensuring that single or shared instances are used as needed. This approach not only optimizes performance but also promotes modularity and scalability of applications, allowing developers to focus on application logic rather than on managing object instances.
