Kuidas on Go keeles goroutine'id rakendatud ja hallatud?

In Go, goroutines are lightweight execution threads managed by the Go runtime, not the operating system. They allow writing concurrent code with minimal resource usage.

Key aspects of implementing and managing goroutines:

• Creation: A goroutine is started with the keyword go before calling a function.
• Scheduler: The Go runtime has its own scheduler that distributes goroutines across system threads (M:N scheduling).
• Stack: Each goroutine has a dynamic stack that can grow and shrink as needed, starting with a few kilobytes.
• Communication: Channels are used for synchronization and data exchange between goroutines.

Example of creating a goroutine:

func sayHello() {
    fmt.Println("Hello from goroutine")
}

func main() {
    go sayHello() // starts the goroutine
    time.Sleep(time.Second) // waits for the goroutine to complete
}

Thus, goroutines are an efficient way to execute code in parallel with minimal overhead.
