What is the difference between IoC and Dependency Injection?

IoC, or Inversion of Control, is a design principle where the control of object creation is transferred to a container. Dependency Injection (DI) is a specific implementation of IoC that provides dependencies to a class rather than the class creating them itself.

Can you give me an example of Dependency Injection?

Sure! In a simple example, if you have a class Car that depends on an Engine, instead of the Car creating the Engine, you would inject the Engine into the Car through its constructor.

Why is Dependency Injection beneficial?

Dependency Injection promotes loose coupling, making your code more modular, easier to test, and maintain. It also enhances code reusability.

Are there any downsides to using Dependency Injection?

Yes, while DI has many benefits, it can introduce complexity and make the code harder to follow if overused or misused. It may also lead to performance overhead in some cases.
