When should I use channels in Go?

Channels in Go are used for communication between goroutines. They help synchronize data and manage concurrency.

Can you give me an example of using channels?

Sure! You can use a channel to send data from one goroutine to another, like this: ch := make(chan int) and then go func() { ch <- 42 }().

What are the benefits of using channels?

Channels provide a safe way to share data between goroutines, preventing race conditions and making your code cleaner.

Are there any downsides to using channels?

Yes, overusing channels can lead to complexity and performance issues. It's important to use them judiciously.
