Select StatementAdvanced
1Question 1 of 1
goHow does the select statement coordinate communication across multiple channels in Go?
Explanation & Concept
The `select` statement blocks until one of its channel communication cases is ready to execute. If multiple channels are ready simultaneously, one is chosen at pseudo-random.
A `default` clause makes channel communication non-blocking.
Code Example
go
package main
import "fmt"
func main() {
ch1 := make(chan string, 1)
ch1 <- "Message from Ch1"
select {
case msg := <-ch1:
fmt.Println("Received:", msg)
default:
fmt.Println("No messages ready to read.")
}
}How It Works & Key Takeaways
`select` allows goroutines to listen to data streams, cancellation signals, and timers concurrently.
