WordPress Plugin Combine JS Description:
WordPress plugin that combines, minifies, and compresses JS files. The JS files that this plugin combines and minifies must be enqueued by using wp_enqueue_script. The plugin combines and minifies JS and writes the output into files in the uploads directory. This plugin uses jsmin.php – PHP implementation of Douglas Crockford’s JSMin. This plugin combines all local JS files into a single file and includes the file in the footer of the theme (requires wp_footer being used in your theme files). Also see the companion plugin, Combine CSS.
