What are channels in Go and how do they work?

Channels in Go are a way to communicate between goroutines. They allow you to send and receive values, enabling synchronization.

Can you give me an example of how to create and use a channel?

Sure! You can create a channel using make(chan Type). For example, ch := make(chan int) creates a channel for integers.

How do I send and receive data using channels?

You can send data using ch <- value and receive it with value := <-ch. This allows goroutines to communicate.

What happens if I try to send data on a channel that has no receiver?

If there are no receivers, the send operation will block until a receiver is available, preventing data loss.
