objects, and it's a good thing.
Once a browser handles an object like an array, for example, that object belongs to the browser. That means you can access the object from another file in your program when using the same browser. You'll have access to whatever methods and properties belong to that object.
Let's look at it from another perspective.
This means that the array you created is not one big list of numbers or strings. Instead, it's an object with its own methods and properties.
If you access your newly-created array as a normal object, it will have its own methods and properties. These properties are the same ones you defined when you created the array. Methods on this new object can get or set values in the array.
