What is Dependency Injection?
Dependency Injection is a design pattern commonly used in Symfony and React applications to manage dependencies between classes. It allows for the decoupling of components, making them more modular and easier to test. With Dependency Injection, dependencies are injected into a class instead of being created within the class itself. This promotes code reusability, as dependencies can be easily swapped or modified without affecting the class that uses them. In Symfony, Dependency Injection is implemented through the use of a container, which is responsible for managing and resolving dependencies. In React, Dependency Injection can be achieved through the use of libraries like InversifyJS or Awilix. Overall, Dependency Injection is a powerful technique that enhances the flexibility and maintainability of Symfony and React applications.
