Dependency injection is a process where we inject the dependent objects rather than consumer creating the objects. DI is everywhere in Angular or we can go one step ahead and say Angular cannot work without DI.
For example in the below code “$scope” and “$http” objects are created and injected by the angular framework. The consumer i.e. “CustomerController” does not create these objects himself rather Angular injects these objects.
function CustomerController($scope,$http)
{
// your consumer would be using the scope and http objects
}
