/**
File Name: 15.4-2.js
ECMA Section: 15.4 Array Objects
Description: Whenever a property is added whose name is an array
index, the length property is changed, if necessary,
to be one more than the numeric value of that array
index; and whenever the length property is changed,
every property whose name is an array index whose value
is not smaller than the new length is automatically
deleted. This constraint applies only to the Array
object itself, and is unaffected by length or array
index properties that may be inherited from its
prototype.
