In this article, we'll be taking a look at Angular 2 services - what they are, why you might use them, and how to create them. We'll also be looking at how to inject them into your components so that they can be used. By the end of this article, you should have a good understanding of how to create and use services in Angular 2.
In Angular 2, services are injectable. This means that you can inject them into any component that needs them. Services are singletons, which means that there is only one instance of them in your app. This instance is shared by all components that inject the service.
In conclusion, Angular 2 services are a great way to create reusable code that can be used across your app. They can help you keep your code DRY and make it easier to unit test and debug.
