What are Angular modules and how do they work?
Angular modules are containers for a cohesive block of code dedicated to an application domain, a workflow, or a set of capabilities. They help organize an application into cohesive blocks.
Can you explain how dependency injection works in Angular?
Dependency injection in Angular is a design pattern used to implement IoC (Inversion of Control), allowing 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 code reusability, testability, and maintainability by decoupling the creation of dependencies from their usage.
Can you give an example of how to implement dependency injection?
Sure! You can use the @Injectable decorator to define a service and then inject it into a component's constructor.
