Example
By default communication over the channcels is sync; when you send some value there must be a receiver. Otherwise you will get fatal error: all goroutines are asleep - deadlock! as follows:
package main
import "fmt"
func main() {
msg := make(chan string)
msg <- "Hey There"
go func() {
fmt.Println(<-msg)
}()
}
Bu there is a solution use: use buffered channels :
package main
import "fmt"
import "time"
func main() {
msg :=make(chan string, 1)
msg <- "Hey There!"
go func() {
fmt.Println(<-msg)
}()
time.Sleep(time.Second * 1)
}
