Kas on võimalik olukord, kus goroutine katkestatakse või see lõpetab iseenda?

In Go, the execution of a goroutine can terminate on its own in several cases:

• The goroutine has finished its function. As soon as the function run inside the goroutine completes, the goroutine ends.
• Panic inside the goroutine. If a panic occurs inside the goroutine and is not recovered, it will terminate abruptly.
• Cancellation via context. If the goroutine listens for a cancellation signal through context.Context and receives it, it can terminate properly.

It is important to understand that goroutines are not forcibly interrupted from outside — you need to implement a stop mechanism yourself, for example, through channels or contexts.

Example of using context to cancel a goroutine:

ctx, cancel := context.WithCancel(context.Background())

go func(ctx context.Context) {
    for {
        select {
        case <-ctx.Done():
            fmt.Println("Goroutine finished")
            return
        default:
            // work
        }
    }
}(ctx)

// At some point, call cancel()
cancel()

This way, the goroutine either finishes on its own after completing its work, or upon receiving a cancellation signal if it is set up to do so.
