// In a [previous](range) example we saw how `for` and
// `range` provide iteration over basic data structures.
// We can also use this syntax to iterate over
// values received from a channel.
package main
import "fmt"
func main() {
// We'll iterate over 2 values in the `queue` channel.
queue := make(chan string, 2)
queue <- "one"
queue <- "two"
close(queue)
// This `range` iterates over each element as it's
// received from `queue`. Because we `close`d the
// channel above, the iteration terminates after
// receiving the 2 elements.
for elem := range queue {
fmt.Println(elem)
