Go is not an object-oriented language in the traditional sense, as it does not support some of the key features typically associated with object-oriented programming (OOP), such as inheritance and classes. However, Go does support many of the principles of OOP, but it implements them differently compared to languages like Java or C++.
In Go, the concept of classes is replaced by structs, which can contain both data and methods. While Go does not have inheritance, it promotes the use of composition over inheritance, which is a principle that many OOP languages encourage as a best practice. Composition in Go is achieved by embedding one struct into another, which allows one to extend the behavior of a struct.
Go also supports interfaces, which are used to define behavior. An interface in Go is a set of method signatures, and any type that implements those methods satisfies the interface. This is a form of polymorphism, one of the core concepts of OOP, where a single interface can represent multiple types.
Encapsulation, another OOP principle, is achieved in Go through the visibility rules of identifiers. If an identifier starts with an uppercase letter, it is exported (visible outside its package), and if it starts with a lowercase letter, it is not exported (not visible outside its package). This allo...
