Go by Example: Channels

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) }`

When we run the program the `"ping"` message is successfully passed from one goroutine to another via our channel.	`$ go run channels.go ping`
By default sends and receives block until both the sender and receiver are ready. This property allowed us to wait at the end of our program for the `"ping"` message without having to use any other synchronization.
