Comment (by johnbillion):

 Example of a naïve JavaScript templating app class which wants to be able
 to access the page template hierarchy:

 {{{
 function __construct() {
         add_filter( 'page_template_hierarchy', array( $this,
 'log_page_template_hierarchy' ) );
         add_action( 'wp_footer',               array( $this,
 'output_page_template_hierarchy' ) );
 }

 public function log_page_template_hierarchy( array $templates ) {
         $this->page_templates = $templates;
         return $templates;
 }

 public function output_page_template_hierarchy() {
         ?>
         <script>
         var page_templates = <?php echo wp_json_encode(
 $this->page_templates ); ?>;
         </script>
         <?php
 }
 }}}
