How does DI relate to Inversion of Control (IoC)?
Inversion of Control (IoC) is a broader principle where control over object creation and
dependency resolution is transferred from the class itself to an external framework or
container.
Dependency Injection is a specific implementation of IoC, where the dependencies are
injected into a class rather than the class creating them internally. So, DI is one way to
achieve IoC.
