Dependency injection for beginners

This article introduces the concept of dependency injection for beginners, using an analogy of building cars with different engines and wheels. It explains the pitfalls of using inheritance for this purpose and contrasts it with the principle of 'composition over inheritance'. The tutorial shows how dependency injection leads to more maintainable and reusable code by decoupling object creation from object behavior.
