Define an Aliased Class Provider in Angular

Aliased providers in Angular allow us to overwrite a provider with another existing provider, so basically create an alias. This is particularly useful if you either don’t have access to the provider you’re aliasing, or when you’re performing a larger refactoring and you don’t want to replace all occurrences right upfront. In this lesson we are going to look also at the key difference between aliasing a provider and simply overwriting it.
