Summary - Goroutines

Combine goroutines to write a parallel task.

In this section you learned goroutines:

Now you will combine these to write a parallel task: start a goroutine, wait with WaitGroup, print status with fmt.Println.

Exercise Print a parallel task

Inside main, add a go func(){...}() expression and print parallel done with fmt.Println.

Show example solution

package main

import "fmt"

func main() {
    go func() {
        fmt.Println("paralel tamam")
    }()
    fmt.Println("paralel tamam")
}

Inside main, print parallel work with fmt.Println.

Show example solution

package main

import "fmt"

func main() {
    fmt.Println("paralel iş")
}

WaitGroup usage

var wg sync.WaitGroup
wg.Add(1)
go func() {
    defer ____()
    fmt.Println("ok")
}()
wg.Wait()

Show answer

var wg sync.WaitGroup
wg.Add(1)
go func() {
    defer wg.Done()
    fmt.Println("ok")
}()
wg.Wait()
