`time.Ticker` in Go
===================

The [`time.Ticker`](https://pkg.go.dev/time#Ticker) type in Go is incredibly useful for situations in which [polling](https://en.wikipedia.org/wiki/Polling_(computer_science)) is needed.

The easiest way to use the Ticker is via the [`time.Tick`](https://pkg.go.dev/time#example-Tick) function,
which just provides access to the ticking channel,
which makes it easy to `range` over:

```go
package main

import (
	"fmt"
	"time"
)

func main() {
	for currentTime := range time.Tick(time.Second) {
		fmt.Println("current time: ", currentTime)
	}
}
```

For more control, [`time.NewTicker`](https://pkg.go.dev/time#NewTicker) works wonders ---
there's no better example than the one [from the docs](https://go.dev/play/p/nG23A6LEd19)!
