Select Statement and Channel Patterns

The select statement allows waiting on multiple channel operations.

• It chooses a case that is ready and blocks if none are.
• Useful in fan-in/fan-out patterns, timeout management, and more.
• Acts like a switch but for channels.

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