Pretend using the universal any type interface{} in a function parameter. Say you work with JSON values and you want to get the type of them in order to process them properly.
A type switch may help you because you know the structure/types you get and therefore can safely assume which types you get. (see type switch )
In the example you also see a very handy print function. fmt.Printf("%v\n", res) eventually you know the printf function from C/C++. However the %v let's you print any type you want. Additionally with classes you might want to use %+v to also see the properties.
