Go (Golang) Programming Essentials

Go (Golang) Programming Essentials Introduction

Go is designed to be concise, clean, and efficient. It is easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the feel of a dynamically typed, interpreted language. Be it system admins, network, cloud, or storage engineers, all lessons in our courseware are highly relevant for using Go to craft enterprise solutions. Class is a combination of live instructor demo and hands-on labs.
