use localize in functions.php

add_action('wp_enqueue_scripts' , function(){ 
  wp_localize_script('jquery', 'config_var', URL );
});

and in js file => config_var will equal the config variable value

you can read the php variable inside th js using echo. use like this

var url='<?php echo _URL; ?>';
 alert(url);
