| http://www.w3.org/ns/prov#value | - 2Since the string total is not an integer, adding a total property to an array does not change its length.Arrays are most useful when the property names are integers, but they are still objects, and objects can acceptany string as a property name.It is not useful to use the Object.beget method from Chapter 3 on arrays because it produces an object,not an array.
