[go-nuts] Does errgroup kills non_error_gouroutines

[Amarjeet Anand]

Code from https://pkg.go.dev/golang.org/x/sync/errgroup?tab=doc

var g errgroup.Group
var urls = []string{
        "http://www.golang.org/";,
        "http://www.google.com/";,
        "http://www.somestupidname.com/";,
}
for _, url := range urls {
        url := url
        g.Go(func() error {
                // Fetch the URL.
                resp, err := http.Get(url)
                if err == nil {
                        resp.Body.Close()
                }
                return err
        })
}
if err := g.Wait(); err == nil {
        fmt.Println("Successfully fetched all URLs.")
}


Out of 3, suppose 2 Goroutines will keep running in parallel without error
and while calling “http://www.google.com/”, it got an error.
That will be collected at g.Wait().

My question is Does *errgroup* terminates the other 2 running Goroutines if
the main keeps running?

Or I need to use errgroup.WithContext(ctx) and keep listening this context
if its ctx.Done() and then terminate my goroutine??
