As you know, when using WaitGroup in Go, we used to manually specify how many concurrent functions we would run, and then manually check whether these concurrent operations were complete based on that number. Here’s an example:```gopackage mainimport ("fmt""sync")func main() {var wg sync.WaitGroupwg.Add(1)go func() {fmt.Println("Hello from before Go 1.25")wg.Done()}()wg.Wait()}```With Go 1.25, the WaitGroup.Go function was introduced under the sync package, making it much easier to manage concurrent operations. Since WaitGroup.Go handles the running tasks internally, we no longer need to manually specify the number of concurrent operations or call .Done() after each one. This will likely reduce the error rate in concurrent processing as well.```gopackage mainimport ("fmt""sync")func main() {var wg sync.WaitGroupwg.Go(func() {fmt.Println("Hello from Go 1.25")})wg.Wait()}```This is a much better and cleaner solution. 👌
