[go] Execute function by timer

Getting Help
1

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?

2

You can use select

package main

import (
	"fmt"
	"time"
)

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.

4

Make it run in its own go routine

Another method is using time.Tick

for range time.Tick(time.Second * 3) {
	println("ping!")
}
