What is the Package level Variable in Golang

by

Golang package-level variable is “defined outside of any function or method”. A package-level variable is visible to all functions and methods within the package and can be accessed using the variable’s name.

To create a package–level variable in Golang, “declare it outside any function or method”. You can access it anywhere in your package because the scope is bigger and wider now.

Example

package main

import (
  "fmt"
)

var data int = 21

func main() {
  fmt.Println(data)
}

Output

21

We defined an integer variable “data” at the package level and not inside a function, but we are accessing the “data” variable inside the main() function.

We can access a variable inside the main() function because the variable is package-level and not at any function level. That’s why it is a global variable that can be accessed anywhere in the script.
