Google Map with Vanilla JavaScript

I am working with google API’s specifically the map API but I get an error.
here is a link to the code

I need a codecademer to help fix the bug so I can get a map on the site.

Not familiar with this API, but the URL looks strange…

.../api/js?key=&&callback=initMap"
               ^
     Is this the key?

Yes Sir, I omitted the key. I was asked not to share my API key.
You can go to developers.google.com/maps.
Hope to get a solution today.
Thanks
