Can channels be used as a mechanism for coordinating task execution between goroutines?

Yes, in Go, channels are the primary mechanism for coordinating and synchronizing the execution of tasks between goroutines. They allow safe data transfer between goroutines, while blocking the sender or receiver until the other side is ready.

Example of using a channel for coordination:

ch := make(chan int)
go func() {
    // Perform task
    ch <- 1 // Send completion signal
}()

// Wait for signal from goroutine
<-ch

Thus, channels help prevent data races and simplify synchronization between goroutines.
