Go is an open source programming language that makes it easy to build simple, reliable, and efficient software. It is used frequently in the container ecosystem by projects such as Kubernetes (container orchestration), Docker (containers), and Cilium (BPF networking).

This playlist is a collection of videos that will start you off on your Golang journey.

Go is an open source programming language that makes it easy to build simple, reliable, and efficient software. Here's how to install the language for development on macOS

Installing Go on macOS

We'll cover a small Golang program that prints a string to the terminal, showing how to set up an executable program, import a package, and build a binary.

Getting Started with Hello World in Go

Functions are as useful in Go as many other programming languages. In this lesson we write a function that operates on numbers covering the func keyword, argument and return signatures, and writing the function body.

Writing a Function that Multiplies a Number by Two in Go

Returning multiple values from a function is a common idiom in Go, most often used for returning values along with potential errors. We'll go over how to return multiple values from a function and use those values in our program.

Returning Multiple Values from a Function in Go

Golang has testing tools built into the standard go tool and the standard library. Here is how to write a unit test on a function so that you can run it with `go test`.

Writing a Unit Test in Go

Constants are expressions whose values are known at compile time, which means that we can generate errors for expressions using those constants at compile time as well, instead of runtime.

Golang Constants Basics

iota is a constant generator that can be used to construct enums. It is effectively an infinite list that starts at 0 that can be used to produce a value for a set of constants.

iota, The Golang Constant Generator

Golang includes the `go mod` command to initialize a new project. Sometimes that command fails even though it tries to be smart about where to get the name of your module from so we give an example of how to explicitly set the name of your go modules based project.

```shell
mkdir my-go-project
cd my-go-project
go mod init github.com/christopherbiscardi/my-go-project
```
