What is Dependency Injection?
Dependency Injection is a design pattern where an object receives its dependencies from an external source rather than creating them itself.
This allows for greater flexibility and modularity, making your code easier to maintain and test.
In Symfony, the Service Container is at the heart of DI. It holds and manages the lifecycle of all your services (classes designed to perform specific tasks).
