| // In Go, there are mainly two types of channel. | |
| // 1. Unbuffered channel | |
| // 2. Buffered channel | |
| // Buffered channel can work asyncronously | |
| // Let's see an example of buffered channel | |
| package main | |
| import ( | |
| "fmt" | |
| "sync" | |
| ) | |
| var msgs []string = []string{"msg1", "msg2", "msg3", "msg4", "msg5"} | |
| var wg sync.WaitGroup | |
| func SendMessage(ch chan string,msg string) { | |
| fmt.Println("Sending msg: ", msg) | |
| ch <- msg | |
| wg.Done() | |
| } | |
| func main() { | |
| len := len(msgs) | |
| wg.Add(len) | |
| bufferedChan := make(chan string, len) | |
| defer close(bufferedChan) | |
| for _,msg := range msgs { | |
| go SendMessage(bufferedChan, msg) | |
| } | |
| wg.Wait() | |
| for i:=0;i<len;i++ { | |
| receivedMsg := <- bufferedChan | |
| fmt.Println("Received msg: ", receivedMsg) | |
