Milline on lipu roll, kui üritad lugeda suletud kanalilt programmeerimiskeeles?

In Go, when reading from a channel, the operation returns two values: the value itself and a boolean flag indicating whether the channel is open.

If the channel is closed and all values have been read, the read returns the zero value of the type and false.

Example:

value, ok := <-ch
if !ok {
    // Channel is closed, further reading is not possible
}

Thus, the ok flag helps determine whether data transmission through the channel has completed and whether to stop reading.
