Change WP_PLUGIN_URL to Template directory

Greetings!

I’ve got a plugin that pulls a js file from the plugin directory, but I
want it to be in the themes’ js directory instead. Can someone tell me how to change the following piece of code to do that?

function add_faq_front_js() {
$pluginPath = WP_PLUGIN_URL.’/’.str_replace(basename( __FILE__),””,plugin_basename(__FILE__));
echo ‘<script type=”text/javascript” src=”‘.$pluginPath.’js/faq-frontend.js”></script>’;
}

Many thanks.
