error at "closeing channels"

there is an error at Chapter 12.
example:

ch := make(chan int)
go func() {
ch <- 1
close(ch)
}()
v, isClosed := <-ch
fmt.Printf("received %d, is channel closed: %v\n", v, isClosed)

here, name "isClosed" doesn't mean "channel is closed", means "is ok to receive an value from channel"

[samuelyao314]

so, the collect code is

ch := make(chan int)
go func() {
ch <- 1
close(ch)
}()
v, ok := <-ch
if !ok {
fmt.Printf("received %d, channel closed\n", v)
}
