| _Channels_ are the pipes that connect concurrent goroutines. You can send values into channels from one goroutine and receive those values into another goroutine. | ||
package main |
||
import "fmt" |
||
func main() { |
||
| Create a new channel with `make(chan val-type)`. Channels are typed by the values they convey. | messages := make(chan string) |
|
| _Send_ a value into a channel using the `channel <-` syntax. Here we send `"ping"` to the `messages` channel we made above, from a new goroutine. | go func() { messages <- "ping" }() |
|
| The `<-channel` syntax _receives_ a value from the channel. Here we'll receive the `"ping"` message we sent above and print it out. | msg := <-messages |
|
fmt.Println(msg) |
ping |
|
} |
