Overview

Golang is an open-source programming language created by Google. As one of the fastest-growing languages in terms of popularity, it’s a great time to pick up the basics of Golang! This course is designed to get you up and running as fast as possible with Go. We’ll quickly cover the basics, then dive into some of the more advanced features of the language.

• Understand the basic syntax and control structures of the language of Golang
• Apply Go’s “OOP” – Structs, Interfaces, Encapsulation, Inheritance, Polymorphism

Prerequisites

Should have programmed in any other language like Java/C#/C/C++/etc.
