Go - Main Package

Package main is special:

• It defines a standalone executable program (Not a library)
• The main package must have a package name main
• It must define a function named main where the execution of the program begins
• Program execution begins by initializing the main package and then invoking the function main

package main
import "fmt"
// The `main` function is the entry point of the program and is executed
// when the program is run, it takes no arguments and returns no values.
func main() {
  // When the `main` function returns, the program exits.
	fmt.Println("Hello, World!")
}
