Kanallar yordamida goroutinlar orasida bajarilishni sinxronlash mumkin. Quyida goroutinaning tugashini kutish uchun bloklovchi qabul (receive) ishlatilgan.

package main

import (
    "fmt"
    "time"
)

// Goroutina ichida ishlaydigan funksiya. done kanali ish tugaganini xabar qilish uchun ishlatiladi
func worker(done chan bool) {
    fmt.Print("working...")
    time.Sleep(time.Second)
    fmt.Println("done")

    // Tugaganimizni bildirish uchun qiymat yuboramiz
    done <- true
}

func main() {
    // Worker'ga berish uchun kanal yaratamiz (buffer=1)
    done := make(chan bool, 1)
    go worker(done)

    // Worker'dan xabar kelguncha bloklanib turamiz
    <-done
}

Terminalda bajarish:

$ go run channel-synchronization.go      
working...done

Agar yuqoridagi dasturdan <-done qatorini olib tashlasangiz, worker ishga tushishidan oldin dastur yakunlanib qoladi. Bir nechta goroutinalarni kutish kerak bo'lsa, amaliyotda sync.WaitGroup ishlatish ma'qul.
