Am learning Go and here in this example, i can see that select statement lets a goroutine wait on multiple communication operations
Do we really need a select statement ? My below does the same without select statement
func runForChannel1(channel1 chan string) {
time.Sleep(1 * time.Second)
channel1 <- "Hi Arun ... I am Channel-1"
}
func runForChannel2(channel2 chan string) {
time.Sleep(2 * time.Second)
channel2 <- "Hi Arun ... I am Channel-2"
}
func testSelect() {
channel1 := make(chan string)
channel2 := make(chan string)
go runForChannel1(channel1)
go runForChannel2(channel2)
chval1, chval2 := <-channel1, <-channel2
fmt.Println(chval1, chval2)
}
func main() {
testSelect()
}
Without the select statment, i was able to wait for both the channels to get their values... Why we would need Select statement ? Can someone educate me please ?
