Introduction

Introduction and Installation

Advantages of Go:

Simple syntax(?)
Fast compilation
Static linking
Concurrency (goroutines and channels)
Garbage collection
Simple language specification
Tooling
- /usr/bin/gofmt (golang-bin package)
- /usr/bin/golint (golint package)
- go help vet
- go help tool

Used as the basis for Docker and Kubernetes.

Third-party tooling, IDEs, etc.
