Go follows a minimalistic approach for its type system. It provides several built-in types such as string, bool, int and float64. Go supports composite types such as array, slice, map and channel. See more In Go, structs are the way to create user-defined concrete types. The design of the struct type is unique compared to other programming … See more Interface types provide contracts to concrete types, which lets you define behaviors for your objects. Let’s create an interface type for specifying the behavior for Person objects. See more Go’s type system does not support inheritance. In Go, composition is preferred over inheritance where type embedding is the way to implement composition. Many pragmatic developers are proponents of … See more In Code Listing – 6, we defined an interface for implementing into Person objects. Let’s implement these behaviors to our concrete types.
