What is a Package?

• A focused area of functionality
• Most Go programs are broken into multiple packages
• Each directory in a go program is associated with a unique package

How to use a Package?

• We use packages by importing them

import (
    "fmt"  // package1
    "strings" //package2
)
// How we use the functions/variables contained in a imported package
// packagename.function()or variable
fmt.Println("This is how we use the functions from imported packages")

• In Go programming language packages can be define in three categories. They are

  1. Own packages (Packages you create)
  2. Third-party packages (Packages created by someone)
  3. Packages that are in Go standard library

• In a package if we want to make variable/function public then the first letter should be capitalized

• Using relative path for importing local packages is considered bad practice
