//We often want to execute Go code at some point in the future, or repeatedly at some interval.
// Go’s built-in timer and ticker features make both of these tasks easy. We’ll look first at timers and then at tickers.
//f you just wanted to wait, you could have used time.Sleep. One reason a timer may be useful is that you can cancel the timer before it expires. Here’s an example of that.
