Hi Karan,

Thanks for writing this course, it is super helpful.

A quick question on this topic.

The following code snippet works,

func main() {
	ch := make(chan string)
	go func() {
		ch <- "Hello"
	}()
	fmt.Println("message", <-ch)
}

However, this doesn't

func main() {
	ch := make(chan string)
	ch <- "Hello"
	fmt.Println("message", <-ch)
}

The only difference is sending a message via a new go routine vs. the same go routine (main). Just curious.
