As shown below, the file begins with an opening bracket [ , so the entire object is an array. The geolocation object contains further key:value pairs, and an array called coordinates.

With a slight change, we can extract the last 10 objects from the array. We can also apply slicing to strings. We can also see a specific object in its entirety.
