Kuidas toimub andmete lugemine mitmest voost või kanalist korraga?

In Go, to read from multiple channels simultaneously, the select operator is used. It allows waiting for data from multiple channels and reacting to the first available.

Example:

ch1 := make(chan int)
ch2 := make(chan int)

go func() { ch1 <- 1 }()
go func() { ch2 <- 2 }()

select {
case val := <-ch1:
    fmt.Println("Received from ch1:", val)
case val := <-ch2:
    fmt.Println("Received from ch2:", val)
}

This way, select blocks until data appears in one of the channels, and then executes the corresponding case. This allows efficient handling of multiple data streams at the same time.
