Array data types
For type Object, the individual objects that are stored in the array can include a variety of different kinds of objects such as:
Penguins, monkeys, lemurs, ladybugs, kangaroos, the camera, the light, the ground, etc.
This is because Object is a generic type that includes all objects other than the world.
On the other hand, you cannot mix elements of type Boolean with type Number, etc., because they are different types.
