### Registering scripts
With View object you can register scripts. There are two dedicated methods for it: `registerScript` for inline scripts
and `registerJsFile` for external scripts. Inline scripts are useful for configuration and dynamically generated code.
The method for adding these can be used as follows:
```php
$this->registerScript("var options = ".json_encode($options).";", View::POS_END, 'my-options');
```
First argument is the actual code where we're converting a PHP array of options to JavaScript one. Second argument
determines where script should be in the page. Possible values are:
- `View::POS_HEAD` for head section.
- `View::POS_BEGIN` for right after opening `<body>`.
- `View::POS_END` for right before closing `</body>`.
- `View::POS_READY` for executing code on document `ready` event. This one registers jQuery automatically.
The last argument is unique script ID that is used to identify code block and replace existing one with the same ID
instead of adding a new one.
External script can be added like the following:
```php
$this->registerJsFile('http://example.com/js/main.js');
```
Same as with external CSS it's preferred to use asset bundles for external scripts.

### Layout
A layout is a very convenient way to represent the part of the page that is common for all or at least for most pages
generated by your application. Typically it includes `<head>` section, footer, main menu and alike elements.
You can fine a fine example of the layout in a [basic application template](apps-basic.md). Here we'll review the very
basic one without any widgets or extra markup.
```php
<?php
use yii\helpers\Html;
?>
<?php $this->beginPage(); ?>
<!DOCTYPE html>
<html lang="<?php echo Yii::$app->charset; ?>">
<head>
<meta charset="<?php echo Yii::$app->charset; ?>"/>
<title><?php echo Html::encode($this->title); ?></title>
<?php $this->head(); ?>
</head>
<body>
<?php $this->beginBody(); ?>
<div class="container">
<?php echo $content; ?>
</div>
<footer class="footer">© 2013 me :)</footer>
<?php $this->endBody(); ?>
</body>
</html>
<?php $this->endPage(); ?>
```
In the markup above there's some code. First of all, `$content` is a variable that will contain result of views rendered
with controller's `$this->render()` method.

### Partials
Often you need to reuse some HTML markup in many views and often it's too simple to create a full-featured widget for it.
