Summary - Channels

Combine channel concepts to write a worker.

In this section you learned channels:

Now you will combine these to write a worker: create a channel, start a goroutine, receive and print.

Exercise Worker channel

Inside main, add a make(chan string) call and print worker done with fmt.Println.

Show example solution

package main

import "fmt"

func main() {
    ch := make(chan string)
    go func() { ch <- "worker tamam" }()
    fmt.Println(<-ch)
}

Inside main, print channel worker with fmt.Println.

Show example solution

package main

import "fmt"

func main() {
    fmt.Println("channel worker")
}

Channel usage

ch := make(chan string)
go func() {
    ch <- ____
}()
msg := <-ch

Show answer

ch := make(chan string)
go func() {
    ch <- "ok"
}()
msg := <-ch
