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:

akhan4u

#! /bin/bash

# ECHO COMMAND
# echo Hello World!

# VARIABLES
# Uppercase by convention
# Letters, numbers, underscores
NAME="Bob"
# echo "My name is $NAME"

akhan4u

#!/bin/sh
# Only Run If Any Cloudformation Template Is Modified And Checks Linting Of The Template

RED='\033[0;31m'
GREEN='\033[0;32m'
NC='\033[0m'
#------------------

FILES=$(git diff --cached --name-only --diff-filter=ACMR "*.yml" "*.yaml" | sed 's| |\\ |g')
