michael@0 8 File Name: 15.4.4.3-1.js
michael@0 9 ECMA Section: 15.4.4.3-1 Array.prototype.reverse()
michael@0 10 Description:
michael@0 11
michael@0 12 The elements of the array are rearranged so as to reverse their order.
michael@0 13 This object is returned as the result of the call.
michael@0 14
michael@0 15 1. Call the [[Get]] method of this object with argument "length".
michael@0 16 2. Call ToUint32(Result(1)).
michael@0 17 3. Compute floor(Result(2)/2).
michael@0 18 4. Let k be 0.
michael@0 19 5. If k equals Result(3), return this object.
michael@0 20 6. Compute Result(2)k1.
michael@0 21 7. Call ToString(k).
michael@0 22 8. ToString(Result(6)).
michael@0 23 9. Call the [[Get]] method of this object with argument Result(7).
michael@0 24 10. Call the [[Get]] method of this object with argument Result(8).
michael@0 25 11. If this object has a property named by Result(8), go to step 12; but
michael@0 26 if this object has no property named by Result(8), then go to either
michael@0 27 step 12 or step 14, depending on the implementation.
michael@0 28 12. Call the [[Put]] method of this object with arguments Result(7) and
michael@0 29 Result(10).
michael@0 30 13. Go to step 15.
michael@0 31 14. Call the [[Delete]] method on this object, providing Result(7) as the
michael@0 32 name of the property to delete.
michael@0 33 15. If this object has a property named by Result(7), go to step 16; but if
michael@0 34 this object has no property named by Result(7), then go to either step 16
michael@0 35 or step 18, depending on the implementation.
michael@0 36 16. Call the [[Put]] method of this object with arguments Result(8) and
michael@0 37 Result(9).
michael@0 38 17. Go to step 19.
michael@0 39 18. Call the [[Delete]] method on this object, providing Result(8) as the
michael@0 40 name of the property to delete.
michael@0 41 19. Increase k by 1.
michael@0 42 20. Go to step 5.
michael@0 43
michael@0 44 Note that the reverse function is intentionally generic; it does not require
michael@0 45 that its this value be an Array object. Therefore it can be transferred to other
michael@0 46 kinds of objects for use as a method. Whether the reverse function can be applied
michael@0 47 successfully to a host object is implementation dependent.
michael@0 48
michael@0 49 Note: Array.prototype.reverse allows some flexibility in implementation
michael@0 50 regarding array indices that have not been populated. This test covers the
michael@0 51 cases in which unpopulated indices are not deleted, since the JavaScript
michael@0 52 implementation does not delete uninitialzed indices.
