title: Statements
---

We're not limited to declaring reactive _values_ — we can also run arbitrary _statements_ reactively. For example, we can log the value of `count` whenever it changes:

```js
$: console.log('the count is ' + count);
```

You can easily group statements together with a block:

```js
$: {
	console.log('the count is ' + count);
	alert('I SAID THE COUNT IS ' + count);
}
```

You can even put the `$:` in front of things like `if` blocks:

```js
$: if (count >= 10) {
	alert('count is dangerously high!');
	count = 9;
}
```
