/**
* Registers a JS file.
* @param string $url the JS file to be registered.
* @param array $options the HTML attributes for the script tag. The following options are specially handled
* and are not treated as HTML attributes:
*
* - `depends`: array, specifies the names of the asset bundles that this JS file depends on.
* - `position`: specifies where the JS script tag should be inserted in a page. The possible values are:
* * [[POS_HEAD]]: in the head section
* * [[POS_BEGIN]]: at the beginning of the body section
* * [[POS_END]]: at the end of the body section. This is the default value.
*
* Please refer to [[Html::jsFile()]] for other supported options.
*
* @param string $key the key that identifies the JS script file. If null, it will use
* $url as the key. If two JS files are registered with the same key, the latter
* will overwrite the former.
