Creating a Function in Golang

A declaration begins with the func keyword, followed by the name you want the function to have, a pair of parentheses (), and then a block containing the function's code.

The following example has a function with the name SimpleFunction. It takes no parameter and returns no values.

Example

package main

import "fmt"

// SimpleFunction prints a message
func SimpleFunction() {
	fmt.Println("Hello World")
}

func main() {
	SimpleFunction()
}

Output

Hello World
