What is the SELECT statement in Go?

Can you explain the SELECT statement in Go?

Sure! The SELECT statement in Go is used to handle multiple channels. It allows a goroutine to wait on multiple communication operations.

How does it differ from a regular switch statement?

Unlike a switch statement, which evaluates cases based on values, SELECT waits for one of its cases to become ready, making it ideal for concurrent programming.

Can you give me a simple example?

Absolutely! Here's a basic example:

select {
case msg1 := <-ch1:
    fmt.Println("Received from ch1:", msg1)
case msg2 := <-ch2:
    fmt.Println("Received from ch2:", msg2)
default:
    fmt.Println("No messages received")
}

What happens if none of the cases are ready?

If none of the cases are ready, the default case will execute if it's present. If there's no default case, the SELECT will block until one of the cases is ready.
