Thanks for sharing these mentoring sessions. I think as a beginner, it can be quite difficult to see which entity or class is implementing the closure, and which class is just declaring it.

I struggled with the concept of closure myself for quite a while to be honest, especially when I was navigating through a large codebase that heavily uses closures at work. It did really hurt my brain for quite sometime.

This reminds me of strategy pattern a lot :P
Also promises are a great way for dealing with async

Thanks for sharing and Paulo for asking this one.

This is a prety common pattern in other languages too. The Kotlin documentation, for example, says "an interface with only one abstract method is called a functional interface, or a Single Abstract Method (SAM) interface", with some sintatic sugar for SAM conversion by the Kotlin compiler.
