What is Dependency Injection?

Dependency injection is a design pattern used in object-oriented programming, where an object receives dependencies from other objects instead of creating them internally. This allows for greater flexibility and makes the code easier to maintain, making it more modular and reusable.

In practice, dependency injection is implemented through interfaces and classes that receive dependencies as parameters in their constructors or methods, rather than instantiating them directly. This makes it easier to swap implementations and makes the code more testable and decoupled.

One of the main benefits of dependency injection is the reduction in code complexity, since dependencies are managed externally and are not directly coupled to the object that uses them. This makes maintenance easier and avoids the creation of unwanted dependencies.

In addition, dependency injection promotes code reuse, since dependencies can be shared between different objects without the need for duplication. This results in cleaner, more organized code that is easier to maintain.

In summary, dependency injection is a fundamental practice in object-oriented programming, which aims to make code more flexible, modular, testable and decoupled. By adopting this design pattern, developers can create more robust and scalable applications, making it easier for software to evolve over time.
