Each data field in a struct is declared with a known type, which could be a built-in type or another user-defined type. It useful when you want to create a one-time usable structure. But the cool thing about Go is that, when we use an anonymous nested struct, all the nested struct fields are automatically available on parent struct. Golang has the ability to declare and create own data types by combining one or more types, including both built-in and user-defined types. Introduction.
