channel

func main() {m := make(chan int64, 10)
    fmt.Println(len(m), cap(m))
}

func main() {
    var wg sync.WaitGroup
    for i := 0; i < 10; i++ {wg.Add(1)

        go func() {fmt.Println("Hello world")
            wg.Done()}()}
    wg.Wait()}


func test3() {_ = make(map[chan interface{}]interface{})
