WaitGroup goroutine pattern can use 'WaitGroup.Go'

Reports the common WaitGroup pattern that uses wg.Add(1), starts a goroutine, and defers wg.Done().

In Go 1.25 and later, (*sync.WaitGroup).Go(func()) combines these steps in one call. This keeps the goroutine launch and the WaitGroup accounting together and reduces boilerplate code.

Example:

func Fanout(tasks []func()) {
	var wg sync.WaitGroup
	for _, task := range tasks {
		wg.Add(1)
		go func() {
			defer wg.Done()
			task()
		}()
	}
	wg.Wait()
}

To fix the code, use the Simplify by using WaitGroup.Go quick-fix.

After the quick-fix is applied:

func Fanout(tasks []func()) {
	var wg sync.WaitGroup
	for _, task := range tasks {
		wg.Go(func() {
			task()
		})
	}
	wg.Wait()
}
