Without goroutine

Regular functions calls are executed sequentially. Each call can only start after all the previous calls have finished.

package main

import (
    "fmt"
    "time"
)

func count(n int, name string) {
    for i := 0; i < n; i++ {
        fmt.Printf("%s %d\n", name, i)
        time.Sleep(1000)
    }
}

func main() {
    fmt.Println("Welcome")
    count(3, "first")
    count(3, "second")
    count(3, "third")
    count(3, "fourth")
    fmt.Println("Done")
