gticker is time ticker with immediate first tick.
The Go standard library has a really cool type – Ticker. Tickers are used when you want to do something at a regular interval. However, if we want to tic immediately the first time, we can cut it out to a function and call it before tic. This package was created for the purpose of being able to handle a different approach from that implementation.

done := make(chan bool)
go func() {
for {
select {
case <-done:
return
case t := <-ticker.C():
fmt.Println("Tick at", t)
}
}
}()
time.Sleep(3 * time.Second)
ticker.Stop()
done <- true
fmt.Println("Ticker stopped")
}
