Package Main and fmt.Println

Read this chapter, write the program on this page, then pass a short check to open the next one.

Your first Go program.

Package Main and fmt.Println

Every executable Go program is package main. Import fmt and call fmt.Println to print a line.

package main is required for executables.
import "fmt" brings in formatting helpers.
func main() is the entry point.

package main

import "fmt"

func main() {
    fmt.Println("Greetings from Golang!")
}
