Project structure

Go programs are organized into packages
A package is a collection of Go files

• create a helper.go file to include function used in main
• moving forward, use go run main.go helper.go to run code

Multiple packages

Create helper folder to locate helper.go file

Hence, specify import of helper package to use functions

Export a variable/function

To make a variable available for all packages in the app, capitalize the first letter of the name
