In this section, I want to emphasize the importance of using the utility function inject() for service or component injection, rather than relying on the traditional constructor-based approach. The inject() function is more flexible and allows for cleaner, more readable code. It simplifies testing, supports better dependency management, and aligns with Angular's ongoing improvements to enhance the developer experience. By adopting inject(), you can take advantage of a more modern and efficient way to handle dependency injection in Angular applications.
