In this #Angular tutorial we will continue to explore Angular dependency injection in depth and we will learn what is resolution modifiers in Angular DI and see them in action. We will cover all 4 modifiers like: @Optional() vs @Host() vs @Self() vs @SkipSelf(). Each of this annotation impact on how Angular will be resolving dependencies in the injector tree. I hope you will learn something new from this video, so thank you for your attention and enjoy watching ;)

⚠️ P.s This topic is not so hard however it requires some background of how Angular resolves dependencies by default. The good news is that I have a video about this:
