Concurrency in Go

 Concurrency in Go

Go has built-in concurrency primitives that make it easy to write concurrent programs. Go uses goroutines, which are lightweight threads that allow you to run multiple functions concurrently. You can create a goroutine using the go keyword.

func printNumbers() {

    for i := 0; i < 10; i++ {

        fmt.Println(i)

    }

}

func main() {

    go printNumbers()

    go printNumbers()

    time.Sleep(time.Second)

}

In this example, we create two goroutines that print numbers from 0 to 9 concurrently. We use the time.Sleep() function to pause the main goroutine for a second to allow the other goroutines to finish.
