Channels are the pipes that connect concurrent goroutines. You can send values into channels from one goroutine and receive those values into another goroutine.

Go
Edit 
package main

import "fmt"

func main() {

    messages := make(chan string)

    // Send a value into a channel using the channel <- syntax.
    go func() { messages <- "ping" }()

    // The <-channel syntax receives a value from the channel.
    msg := <-messages
    fmt.Println(msg)
}
