Dependency Injection Insights

What is Dependency Injection?

Dependency Injection (DI) is a design pattern in software engineering where objects receive their dependencies from external sources rather than creating them themselves. This promotes loose coupling, improves testability, and enhances code reusability. It's commonly used in modern frameworks like Spring (Java), Angular (.NET), and others to manage object dependencies effectively.
