Launches 10 Goroutines and each goroutine adding 10 values to a Channel

The program starts with 10 Goroutines. We created a ch string channel and writing data to that channel by running 10 goroutines concurrently. The direction of the arrow with respect to the channel specifies whether the data is sent or received. The arrow points towards ch specifies we are writing to channel ch. The arrow points outwards from ch specifies we are reading from channel ch.

Example

package main

import (
	"fmt"
	"strconv"
)

func main() {
	ch := make(chan string)

	for i := 0; i < 10; i++ {
		go func(i int) {
			for j := 0; j < 10; j++ {
				ch <- "Goroutine : " + strconv.Itoa(i)
			}
		}(i)
	}

	for k := 1; k <= 100; k++ {
		fmt.Println(k, <-ch)
	}
}
