How to Create Your Own Package in Go

Create a new directory for your module, initialize it with go mod init, and write your code in a .go file.

mkdir my-package
cd my-package
go mod init github.com/yourusername/my-package
echo 'package main\n\nimport "fmt"\n\nfunc main() { fmt.Println("Hello") }' > main.go
go build

This creates a module named my-package with a single executable.

Creating a Go package is like setting up a new folder for a specific project. You tell Go the name of your project so it can manage dependencies and build your code correctly. Think of it as creating a labeled box where all your related code lives together.
