The go language execution waits until the background goroutine execution completes the instance analysis

This article illustrates the use of the go language to wait until the goroutine execution is complete. Share with you for your reference. The details are as follows:

var w sync.WaitGroup

w.Add(2)

go func() {

    // do something

    w.Done()

}

go func() {

    // do something

    w.Done()

}

w.Wait()

I hope this article has been helpful to your programming of Go language.
