Function vs Procedure

Perbedaan function dan procedure adalah function mengembalikan suatu nilai, sementara procedure tidak. Prosedur hanya mengeksekusi bari kode saja.

Contoh code function

package main

import "fmt"

func add(x int, y int) int {
    return x + y
}

func main() {
    fmt.Println(add(42, 13))
}

Contoh code prosedur

package main

import (
	"fmt"
)

func main() {
	Introduction("Adi", "programmer", 1, 23)
}

func Introduction(name, job string, experience, age int) {
	fmt.Printf(`
	    Hello, Iam %s,
		I was an %s,
		I have %d experience
		and I am %d old.
	`, name, job, experience, age)
}

Hello, Iam Adi,
		I was an programmer,
		I have 1 experience
		and I am 23 old.
