[Go] Using buffered channels.

package main

import (
    "log"
    "os"
    "sync"
)

func main() {
    // A goroutine-safe console printer.
    logger := log.New(os.Stdout, "", 0)

    // Sync among all goroutines.
    var wg sync.WaitGroup

    // Make a buffered channel.
    ch := make(chan int, 10)

    for i := 1; i <= 10; i++ {
        ch <- i
        wg.Add(1)
        go func() {
            defer wg.Done()
            logger.Println("Print from goroutine ", <-ch)
        }()
    }

    logger.Println("Print from main")
    wg.Wait()
}
