Describing behavior rather than implementation: Interfaces in Go

Despite not having Object Oriented Programming (OOP) language features, Go does have interfaces.

Interfaces allow you to interchange what data types you are passing as arguments to a function, as long as that type has the required methods.

Interfaces in Go are different compared to, say, C# or Java, in that you don't have to explicitly state you are implementing an interface, which is pretty cool.
