Channels

A channel carries values between goroutines. chan T is bidirectional; chan<- T is send-only; <-chan T is receive-only.

Create a buffered channel.

ch := make(chan int, 1)      // buffered, cap 1

Send.

ch <- 42

Receive.

v := <-ch

See Concurrency for the full coordination surface (select, close, range over channels).
