Unlike C++, new and delete in JavaScript are not related to each other. The
keyword new constructs a new object. However, the keyword delete removes a
*property* from an object. The value named by the property will not
necessarily be garbage collected---there may be other references to it. The
value is normally not deallocated immediately in any case.
Properties introduced with 'var' are not deletable, so 'delete' correctly
does not delete the property.

Properties introduce with 'var' are not deletable. Most other properties
are.
