<# Syntax in WordPress

1 comment

1. If you look into wp-includes/js/wp-util.js, you’ll find the following function that parse those tags:

   wp.template = _.memoize(function ( id ) {
       var compiled,
           /*
            * Underscore's default ERB-style templates are incompatible with PHP
            * when asp_tags is enabled, so WordPress uses Mustache-inspired templating syntax.
            *
            * @see trac ticket #22344.
            */
           options = {
               evaluate:    /<#([sS]+?)#>/g,
               interpolate: /{{{([sS]+?)}}}/g,
               escape:      /{{([^}]+?)}}(?!})/g,
               variable:    'data'
           };
   
       return function ( data ) {
           compiled = compiled || _.template( $( '#tmpl-' + id ).html(), null, options );
           return compiled( data );
       };
   });
   

   As the comment explain, they changed the template tag <% %> to Mustache tags in version 3.5 to avoid any conflict with asp tags.
