/**
* Outputs customizer JavaScript
*
* This function automatically outputs theme customizer preview JavaScript for each theme option,
* where the `preview_js` property is set.
*
* For CSS theme option change it works by inserting a `<style>` tag into a preview HTML head for
* each theme option separately. This is to prevent inline styles on elements when applied with
* pure JS.
* Also, we need to create the `<style>` tag for each option separately so way we gain control
* over the output. If we put all the CSS into a single `<style>` tag, it would be bloated with
* CSS styles for every single subtle change in the theme option(s).
*
* It is possible to set up a custom JS action, not just CSS styles change. That can be used
* to trigger a class on an element, for example.
*
* If `preview_js => false` set, the change of the theme option won't trigger the customizer
* preview refresh. This is useful to disable "about theme page", for example.
*
* The actual JavaScript is outputted in the footer of the page.
*
* Use this structure for `preview_js` property:
*
* @example
*
* 'preview_js' => array(
*
* // Setting CSS styles:
*
* 'css' => array(
*
* // Sets the whole value to the `css-property-name` of the `selector`
*
* 'selector' => array(
* 'css-property-name',...
* ),
*
* // Sets the `css-property-name` of the `selector` with value followed by the `suffix` (such as "px")
*
* 'selector' => array(
* array( 'css-property-name', 'suffix' ),...
* ),
*
* // Replaces "@" in `selector` for `selector-replace-value` (such as "@ h2, @ h3" to ".footer h2, .footer h3")
*
* 'selector' => array(
* 'selector_replace' => 'selector-replace-value', // Must be the first array item
* 'css-property-name',...
* ),
*
* ),
*
* // Or setting custom JavaScript:
*
* 'custom' => 'JavaScript here', // Such as "jQuery( '.site-title.type-text' ).toggleClass( 'styled' );"
*
* );
