Millised on gorutinate kasutamise eelised võrreldes traditsiooniliste lõngadega mitmetöötlusprogrammeerimises?

Goroutines in Go have several advantages over traditional threads:

• Lightweight: Goroutines occupy much less memory (usually a few kilobytes), whereas OS threads require megabytes.
• Fast creation and switching: Starting and switching between goroutines is significantly faster than between OS threads.
• Scheduler management: The Go runtime automatically manages the goroutine scheduler and efficiently distributes goroutines across OS threads.
• Simple synchronization: Built-in channels allow easy and safe data exchange between goroutines without complex synchronization primitives.

Example of using goroutines and channels:

func worker(ch chan int) {
    for val := range ch {
        fmt.Println("Received:", val)
    }
}

func main() {
    ch := make(chan int)
    go worker(ch) // start goroutine
    ch <- 42
    close(ch)
}

Thus, goroutines provide an efficient and convenient means for concurrent programming, with fewer resources and simpler code compared to traditional threads.
