How does AngularJS handle dependency injection?

Certainly, I'm glad you asked about AngularJS's dependency injection system, as it's one of the core features that makes AngularJS particularly powerful and efficient for developing dynamic web applications. Having utilized AngularJS extensively in my projects as a Frontend Developer, I've leveraged dependency injection to create more maintainable, readable, and testable code. At its core, dependency injection in AngularJS is a design pattern that allows a component or function to receive its dependencies from an external source rather than creating them internally. This means that when we define components, such as controllers, services, or directives in AngularJS, we don't hard-code their dependencies. Instead, we list these dependencies as parameters in the component's definition, and AngularJS takes care of instantiating and injecting them at runtime...
