2020-09-01 The Channel Closing Principle One general principle of using Go channels is don't close a channel from the receiver side and don't close a channel if the channel has multiple concurrent senders. In other words, we should only close a channel in a sender goroutine if the sender is … go func {for {select {case <-done: return case t:= <-ticker. C: fmt. Println ("Tick at", t)}}}() Tickers can be stopped like timers. Once a ticker is stopped it won’t receive any more values on its channel. We’ll stop ours after 1600ms. time.

Go channels are a way to communicate between two goroutines. Reading data on a channel is simple, just use the receive operator: ch:= make (chan int) go func {fmt. Printf ("%d \n ", <-ch)}() ch <-42. If you need to listen on several channels, you can use the select statement: spawn:= func chan int {ch:= make (chan int) go func {ch <-rand.
