Google Maps API error: MissingKeyMapError

Google Maps API error: MissingKeyMapError, someone asked me to explain?

I got this following error due to google api key not passed as parameter to the URL.

google maps api not working

The Google allows authenticated users to access their APIs using an API key. To get started working with google maps API click the link which will guide you the process of activating it. Once you get the generated API key. You need to pass the parameter API key to the URL. The URL contained in the script tag of the source will load all the symbols and definition of the goolge maps API. 

<script src="https://maps.googleapis.com/maps/api/js?v=3&key=YOUR-KEY" type="text/javascript"></script>

When you pass the input parameter longitude and latitude to the maps JavaScript the google maps API set location you want.

var latlng = new google.maps.LatLng(40.73, -73.93);

        var mapOptions = {

            zoom: 8,

            center: latlng,
