Learn Go in ~5mins

This is inspired by A half-hour to learn Rust and Zig in 30 minutes.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

dlorenc

# First try, we get edb8f4a65586 as our hash
$ cat << EOF | docker build --no-cache -
> FROM alpine
> RUN touch foo
> EOF
Sending build context to Docker daemon  2.048kB
Step 1/2 : FROM alpine
 ---> a24bb4013296
Step 2/2 : RUN touch foo
