What is dependency injection?
Dependency Injection is a design pattern that helps in the creation and management of object dependencies. In Angular, components and services often have dependencies on other components or services, and dependency injection allows these dependencies to be provided to the dependent objects at runtime. This helps in modularity, reusability, and testability in Angular applications.
Purpose of ProvidedIn in Angular
Angular’s dependency injection system is a powerful mechanism that helps manage dependencies between components, services, and other parts of the application. One important aspect of this system is the providedIn property, which determines the scope and visibility of a service or module. In this article, we’ll explore the purpose of providedIn in Angular and how it relates to the overall dependency injection mechanism.
