Millised on gorutinite kasutamise eelised võrreldes lõngadega (threads)?

Gorutines in Go are lightweight threads managed by the Go runtime, not the operating system. Their advantages over traditional threads:

• Less memory consumption: Gorutines occupy a few kilobytes of memory, while threads — megabytes.
• Fast creation and switching: Starting and switching between gorutines is much faster.
• Simple synchronization: Go provides channels for safe data exchange between gorutines, simplifying concurrent programming.
• Scalability: You can launch thousands or even millions of gorutines simultaneously.

Example of creating a gorutine:

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

func main() {
    go sayHello() // start a goroutine
    time.Sleep(time.Second) // wait for the goroutine to complete
}
