How to Fetch Return Value from a goroutine in Golang

package main

import (
  "fmt"
  "time"
)

func main() {

  c1 := make(chan int)
  c2 := make(chan string)

  go func() {
    time.Sleep(2 * time.Second)
    c1 <- 10
  }()

  go func() {
    time.Sleep(time.Second)
    c2 <- "One"
  }()

  // Fetch
  for i := 0; i < 2; i++ {
    // Await both of these values
    // simultaneously, printing each one as it arrives.
    select {
    case m1 := <-c1:
      fmt.Println("received ", m1)
    case m2 := <-c2:
      fmt.Println("received ", m2)
    }
  }

}

$ go run main.go
received  One
received  10
