This article was written by Steve Francia, the author of Hugo. Hugo is an amazing static website engine written in Go. As I’m in the process of learning go I decided to look at Steve’s blog posts trying to find more information about both Hugo and Go.

The article tries to list what makes a programming language support OOP design. It points out a brief information about OOP concepts like:

• Inheritance And Polymorphism;
• Single & Multiple Inheritance;
• Subtyping (Polymorphism);
• Object Composition

The article describes how and which of those concepts Go supports.

Steve, as most part of modern software development communities, considers Inheritance as a bad practice. In order to fundament his opinion Steve quotes James Gosling (Java’s inventor) and mentions that GoF book discusses at length replacing implementation (extends) with interface inheritance (implements).
