Features of Providedln
- Scoping and Visibility: By controlling the scope of services, you can ensure that they are only available where they are needed that helps in better code organization and maintainability.
- Singleton vs. Multiple Instances: Depending on your application’s requirements, you can choose to have a single instance of a service shared across the entire application or multiple instances for different modules or components.
- Lazy Loading: When using the Angular module system with lazy loading, specifying the providedIn property correctly can help optimize your application’s performance by ensuring that services are only loaded when needed.
