Скачать или смотреть GO | Interfaces are easier than you think

This is a tutorial about Interfaces in GO/Golang.

In GO, interfaces are commonly used and improve the modularity and decoupling of your code. Interfaces define the behavior of a type. This means, in interfaces one defines the methods that describe the wanted behavior.

In contrast to other programming languages, in GO, interfaces are implemented implicitly. This means, that a type automatically implements an interface if it has all methods that the interface requires.

Also, GO interfaces support polymorphism. This means, that you can change the implementation without changing the context of a type. If a function has an interface as a paramter, you can use all implementations of that interface and pass it to the function.
