Kuidas eristada kanaleid, mida kasutatakse andmete edastamiseks lõimede vahel, gorutinidest nende eesmärgi ja funktsiooni osas?

In Go, goroutines are lightweight execution threads that are started with the go keyword. They execute functions or methods in parallel.

Channels are means of communication between goroutines, allowing safe transfer of data and synchronization of their work.

Main differences:

• Goroutines are code executors that start parallel tasks.
• Channels are data transmission means between goroutines, ensuring message exchange and synchronization.

Example:

func() {
    ch <- 42 // send value to channel
}()
value := <-ch // receive value from channel

Thus, goroutines are "workers", and channels are the "mail" for message exchange between them.
