Concurrency in Go: Fixing WaitGroup

fixed_waitgroup.go

wg := &sync.WaitGroup{}
wg.Add(10)
for i := 0; i < 10; i++ {
       go func(wg *sync.WaitGroup) {
              time.Sleep(1 * time.Second)
              fmt.Println("Finished")
              wg.Done()
       }(wg)
}
wg.Wait()
// Finally works!
