Making the Google Maps API non readable

Question

Our former developers created this code below. However, when it renders on our site, it displays the API key. Is there a better way to hide the API key while still enlisting the script to be executed?

wp_enqueue_script('hw-google-map','https://maps.google.com/maps/api/js?v=3&key=APIKEYTHATISPUBLIC', array('jquery'), 1.1, false);

While you can't obfuscate/hide the code, you can restrict access by domain: https://developers.google.com/maps/api-security-best-practices
