Overview Of Dependency Injection In Angular

Dependency injection is the way of programming in which we try to inject the set of operations called services to the modules. Without dependency injection, if we are creating the application in large scale then we have to repeat the creation certain set of operations everywhere in the application. With the help of Dependency injection we simply create the services that contains the set operations related to creating the data and other manipulations and inject it to everywhere it is using. It allow us to create the loosely coupled application where components are independent of changes done by services externally.
