+
+    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.

+                        the same arguments.
+
+                        An array is created and returned as if by the
+                        expression new Array(len).

+                        given two or more arguments.
+
+                        The [[Prototype]] property of the newly constructed
+                        object is set to the original Array prototype object,
+                        the one that is the initial value of Array.prototype(0)
+                        (15.4.3.1).
+

+                        is set to "Array".
+
+                        If the argument len is a number, then the length
+                        property  of the newly constructed object is set to
+                        ToUint32(len).
+
+                        If the argument len is not a number, then the length
+                        property of the newly constructed object is set to 1
+                        and the 0 property of the newly constructed object is
+                        set to len.

+    File Name:          15.4.4.3-1.js
+    ECMA Section:       15.4.4.3-1 Array.prototype.reverse()
+    Description:
+
+    The elements of the array are rearranged so as to reverse their order.
+    This object is returned as the result of the call.
+
+   1.   Call the [[Get]] method of this object with argument "length".
+   2.   Call ToUint32(Result(1)).
+   3.   Compute floor(Result(2)/2).
+   4.   Let k be 0.
+   5.   If k equals Result(3), return this object.
+   6.   Compute Result(2)k1.
+   7.   Call ToString(k).
+   8.   ToString(Result(6)).
+   9.   Call the [[Get]] method of this object with argument Result(7).
+  10.   Call the [[Get]] method of this object with argument Result(8).
+  11.   If this object has a property named by Result(8), go to step 12; but
+        if this object has no property named by Result(8), then go to either
+        step 12 or step 14, depending on the implementation.
+  12.   Call the [[Put]] method of this object with arguments Result(7) and
+        Result(10).
+  13.   Go to step 15.
+  14.   Call the [[Delete]] method on this object, providing Result(7) as the
+        name of the property to delete.
+  15.   If this object has a property named by Result(7), go to step 16; but if
+        this object has no property named by Result(7), then go to either step 16
+        or step 18, depending on the implementation.
+  16.   Call the [[Put]] method of this object with arguments Result(8) and
+        Result(9).
+  17.   Go to step 19.
+  18.   Call the [[Delete]] method on this object, providing Result(8) as the
+        name of the property to delete.
+  19.   Increase k by 1.
+  20.   Go to step 5.
+
+Note that the reverse function is intentionally generic; it does not require
+that its this value be an Array object. Therefore it can be transferred to other
+kinds of objects for use as a method. Whether the reverse function can be applied
+successfully to a host object is implementation dependent.
+
+    Note:   Array.prototype.reverse allows some flexibility in implementation
+    regarding array indices that have not been populated. This test covers the
+    cases in which unpopulated indices are not deleted, since the JavaScript
+    implementation does not delete uninitialzed indices.

+    File Name:          15.4.4.3-1.js
+    ECMA Section:       15.4.4.3-1 Array.prototype.reverse()
+    Description:
+
+    The elements of the array are rearranged so as to reverse their order.
+    This object is returned as the result of the call.
+
+   1.   Call the [[Get]] method of this object with argument "length".
+   2.   Call ToUint32(Result(1)).
+   3.   Compute floor(Result(2)/2).
+   4.   Let k be 0.
+   5.   If k equals Result(3), return this object.
+   6.   Compute Result(2)k1.
+   7.   Call ToString(k).
+   8.   ToString(Result(6)).
+   9.   Call the [[Get]] method of this object with argument Result(7).
+  10.   Call the [[Get]] method of this object with argument Result(8).
+  11.   If this object has a property named by Result(8), go to step 12; but
+        if this object has no property named by Result(8), then go to either
+        step 12 or step 14, depending on the implementation.
+  12.   Call the [[Put]] method of this object with arguments Result(7) and
+        Result(10).
+  13.   Go to step 15.
+  14.   Call the [[Delete]] method on this object, providing Result(7) as the
+        name of the property to delete.
+  15.   If this object has a property named by Result(7), go to step 16; but if
+        this object has no property named by Result(7), then go to either step 16
+        or step 18, depending on the implementation.
+  16.   Call the [[Put]] method of this object with arguments Result(8) and
+        Result(9).
+  17.   Go to step 19.
+  18.   Call the [[Delete]] method on this object, providing Result(8) as the
+        name of the property to delete.
+  19.   Increase k by 1.
+  20.   Go to step 5.
+
+Note that the reverse function is intentionally generic; it does not require
+that its this value be an Array object. Therefore it can be transferred to other
+kinds of objects for use as a method. Whether the reverse function can be applied
+successfully to a host object is implementation dependent.
+
+    Note:   Array.prototype.reverse allows some flexibility in implementation
+    regarding array indices that have not been populated. This test covers the
+    cases in which unpopulated indices are not deleted, since the JavaScript
+    implementation does not delete uninitialzed indices.

+    File Name:          15.4.4.5.js
+    ECMA Section:       Array.prototype.sort(comparefn)
+    Description:
+
+    This test file tests cases in which the compare function is not supplied.
+
+    The elements of this array are sorted. The sort is not necessarily stable.
+    If comparefn is provided, it should be a function that accepts two arguments
+    x and y and returns a negative value if x < y, zero if x = y, or a positive
+    value if x > y.
+
+   1.   Call the [[Get]] method of this object with argument "length".
+   2.   Call ToUint32(Result(1)).
+        1.  Perform an implementation-dependent sequence of calls to the
+        [[Get]] , [[Put]], and [[Delete]] methods of this object and
+        toSortCompare (described below), where the first argument for each call
+            to [[Get]], [[Put]] , or [[Delete]] is a nonnegative integer less
+            than Result(2) and where the arguments for calls to SortCompare are
+            results of previous calls to the [[Get]] method. After this sequence
+            is complete, this object must have the following two properties.
+            (1) There must be some mathematical permutation of the nonnegative
+            integers less than Result(2), such that for every nonnegative integer
+            j less than Result(2), if property old[j] existed, then new[(j)] is
+            exactly the same value as old[j],. but if property old[j] did not exist,
+            then new[(j)] either does not exist or exists with value undefined.
+            (2) If comparefn is not supplied or is a consistent comparison
+            function for the elements of this array, then for all nonnegative
+            integers j and k, each less than Result(2), if old[j] compares less
+            than old[k] (see SortCompare below), then (j) < (k). Here we use the
+            notation old[j] to refer to the hypothetical result of calling the [
+            [Get]] method of this object with argument j before this step is
+            executed, and the notation new[j] to refer to the hypothetical result
+            of calling the [[Get]] method of this object with argument j after this
+            step has been completely executed. A function is a consistent
+            comparison function for a set of values if (a) for any two of those
+            values (possibly the same value) considered as an ordered pair, it
+            always returns the same value when given that pair of values as its
+            two arguments, and the result of applying ToNumber to this value is
+            not NaN; (b) when considered as a relation, where the pair (x, y) is
+            considered to be in the relation if and only if applying the function
+            to x and y and then applying ToNumber to the result produces a
+            negative value, this relation is a partial order; and (c) when
+            considered as a different relation, where the pair (x, y) is considered
+            to be in the relation if and only if applying the function to x and y
+            and then applying ToNumber to the result produces a zero value (of either
+            sign), this relation is an equivalence relation. In this context, the
+            phrase "x compares less than y" means applying Result(2) to x and y and
+            then applying ToNumber to the result produces a negative value.
+    3.Return this object.
+
+    When the SortCompare operator is called with two arguments x and y, the following steps are taken:
+       1.If x and y are both undefined, return +0.
+       2.If x is undefined, return 1.
+       3.If y is undefined, return 1.
+       4.If the argument comparefn was not provided in the call to sort, go to step 7.
+       5.Call comparefn with arguments x and y.
+       6.Return Result(5).
+       7.Call ToString(x).
+       8.Call ToString(y).
+       9.If Result(7) < Result(8), return 1.
+      10.If Result(7) > Result(8), return 1.
+      11.Return +0.
+
+Note that, because undefined always compared greater than any other value, undefined and nonexistent
+property values always sort to the end of the result. It is implementation-dependent whether or not such
+properties will exist or not at the end of the array when the sort is concluded.
+
+Note that the sort function is intentionally generic; it does not require that its this value be an Array object.
+Therefore it can be transferred to other kinds of objects for use as a method. Whether the sort function can be
+applied successfully to a host object is implementation dependent .

+    File Name:          15.4.4.5-2.js
+    ECMA Section:       Array.prototype.sort(comparefn)
+    Description:
+
+    This test file tests cases in which the compare function is supplied.
+    In this cases, the sort creates a reverse sort.
+
+    The elements of this array are sorted. The sort is not necessarily stable.
+    If comparefn is provided, it should be a function that accepts two arguments
+    x and y and returns a negative value if x < y, zero if x = y, or a positive
+    value if x > y.
+
+   1.   Call the [[Get]] method of this object with argument "length".
+   2.   Call ToUint32(Result(1)).
+        1.  Perform an implementation-dependent sequence of calls to the
+        [[Get]] , [[Put]], and [[Delete]] methods of this object and
+        toSortCompare (described below), where the first argument for each call
+            to [[Get]], [[Put]] , or [[Delete]] is a nonnegative integer less
+            than Result(2) and where the arguments for calls to SortCompare are
+            results of previous calls to the [[Get]] method. After this sequence
+            is complete, this object must have the following two properties.
+            (1) There must be some mathematical permutation of the nonnegative
+            integers less than Result(2), such that for every nonnegative integer
+            j less than Result(2), if property old[j] existed, then new[(j)] is
+            exactly the same value as old[j],. but if property old[j] did not exist,
+            then new[(j)] either does not exist or exists with value undefined.
+            (2) If comparefn is not supplied or is a consistent comparison
+            function for the elements of this array, then for all nonnegative
+            integers j and k, each less than Result(2), if old[j] compares less
+            than old[k] (see SortCompare below), then (j) < (k). Here we use the
+            notation old[j] to refer to the hypothetical result of calling the [
+            [Get]] method of this object with argument j before this step is
+            executed, and the notation new[j] to refer to the hypothetical result
+            of calling the [[Get]] method of this object with argument j after this
+            step has been completely executed. A function is a consistent
+            comparison function for a set of values if (a) for any two of those
+            values (possibly the same value) considered as an ordered pair, it
+            always returns the same value when given that pair of values as its
+            two arguments, and the result of applying ToNumber to this value is
+            not NaN; (b) when considered as a relation, where the pair (x, y) is
+            considered to be in the relation if and only if applying the function
+            to x and y and then applying ToNumber to the result produces a
+            negative value, this relation is a partial order; and (c) when
+            considered as a different relation, where the pair (x, y) is considered
+            to be in the relation if and only if applying the function to x and y
+            and then applying ToNumber to the result produces a zero value (of either
+            sign), this relation is an equivalence relation. In this context, the
+            phrase "x compares less than y" means applying Result(2) to x and y and
+            then applying ToNumber to the result produces a negative value.
+    3.Return this object.
+
+    When the SortCompare operator is called with two arguments x and y, the following steps are taken:
+       1.If x and y are both undefined, return +0.
+       2.If x is undefined, return 1.
+       3.If y is undefined, return 1.
+       4.If the argument comparefn was not provided in the call to sort, go to step 7.
+       5.Call comparefn with arguments x and y.
+       6.Return Result(5).
+       7.Call ToString(x).
+       8.Call ToString(y).
+       9.If Result(7) < Result(8), return 1.
+      10.If Result(7) > Result(8), return 1.
+      11.Return +0.
+
+Note that, because undefined always compared greater than any other value, undefined and nonexistent
+property values always sort to the end of the result. It is implementation-dependent whether or not such
+properties will exist or not at the end of the array when the sort is concluded.
+
+Note that the sort function is intentionally generic; it does not require that its this value be an Array object.
+Therefore it can be transferred to other kinds of objects for use as a method. Whether the sort function can be
+applied successfully to a host object is implementation dependent .
