I was wondering what this mysterious output in the chrome dev console is when I run a timeout with a childElementCount and it seems to increment by one each time I re-run the function.

```js
function Eggs(){
var f = document.getElementById("x").childElementCount;
console.log(f);
}
setTimeout(Eggs(), 3000);
/* output should be:
0
8
in the chrome console */
```

```html
<!DOCTYPE html>
<html>

<body>
    <div>
        <div>
            <div id="x"></div>
        </div>
    </div>
</body>

</html>
```

it works just fine and gives me the correct number of children
