Dependency Injection

Dependency Injection (DI) is a design pattern in which an object's dependencies are provided externally rather than being created within the object itself. This approach promotes loose coupling between components, enhancing the flexibility and testability of the system. DI is often implemented using frameworks and containers that manage the lifecycle and resolution of dependencies, making it easier to configure and maintain complex systems. It is a key practice in achieving a modular and maintainable codebase.

What is the main benefit of using dependency injection?
The main benefit of using dependency injection is promoting loose coupling between components, which enhances the flexibility, testability, and maintainability of the system.
How does dependency injection work in practice?
Dependency injection works by providing an object's dependencies externally, often using frameworks and containers that manage the lifecycle and resolution of these dependencies.
What role do frameworks play in dependency injection?
Frameworks play a crucial role in dependency injection by managing the creation, configuration, and lifecycle of dependencies, making it easier to implement and maintain DI in complex systems.
