How does dependency injection work in Angular?

Can you explain how dependency injection works in Angular?

Sure! Dependency injection (DI) in Angular is a design pattern that allows a class to receive its dependencies from an external source rather than creating them itself.

Why is dependency injection important in Angular?

It's important because it promotes modularity, makes testing easier, and helps manage the lifecycle of services.

Can you give me an example of how to implement it?

Absolutely! You can use the @Injectable decorator to define a service and then inject it into a component's constructor.

What are the benefits of using dependency injection?

The benefits include improved code maintainability, easier testing, and better separation of concerns.
