从调用另一个goroutine的goroutine返回

Question

I wonder what happens to goroutines called from another goroutine when it returns. Do they continue running or get terminated? Here is a sample code to show what I mean:

func func() {
    // Doing something
}

func func2() {
        go func()
        // Doing things that end with a return
    }

func main() {
    go func2()
}

what happens to func() goroutine when func2() goroutine returns?

You can make an experiment on excellent https://play.golang.org playground! I recommend experiment there - it helps very much with golang studying.

I've added 2 second delay, because if program exit too quickly, you 'll not see results from goroutines.
