[go] Execute function by timer

Can you please tell me if there are standard methods in go to start functions on a timer, for example, is it possible to specify a function to execute every 3 seconds?

You can use select

package main

import (

func main() {
	for {
		select {
		case <-time.After(time.Second * 3):
			fmt.Println("Hello, playground")



thank you, but how to make the code run in the background? Because the compiler shows that the code after the for loop will never be executed.

Make it run in its own go routine

Another method is using time.Tick

for range time.Tick(time.Second * 3) {
