Dependency Injection : Optimizing Angular App with Services and DI - Angular 18 tutorial (Part 22)

In this video, we revisit a scenario from our previous tutorial where we faced a challenge in an Angular application. We had a list of programming languages displayed in one component, and a requirement to show detailed information in another. Instead of repeating the same data in multiple components, we solve the problem by introducing services and leveraging Dependency Injection to centralize data access.

Watch as we walk through creating a DataService to handle the languages array and inject it into our components. Learn how using services and DI helps you follow the DRY principle, making your Angular applications more maintainable and efficient.
