| 9 * SUMMARY: arr.sort() should not output |undefined| when |arr| is empty | |
| 10 * See http://bugzilla.mozilla.org/show_bug.cgi?id=178722 | |
| 11 * | |
| 12 * ECMA-262 Ed.3: 15.4.4.11 Array.prototype.sort (comparefn) | |
| 13 * | |
| 14 * 1. Call the [[Get]] method of this object with argument "length". | |
| 15 * 2. Call ToUint32(Result(1)). | |
| 16 * 3. Perform an implementation-dependent sequence of calls to the [[Get]], | |
| 17 * [[Put]], and [[Delete]] methods of this object, etc. etc. | |
| 18 * 4. Return this object. | |
| 19 * | |
| 20 * | |
| 21 * Note that sort() is done in-place on |arr|. In other words, sort() is a | |
| 22 * "destructive" method rather than a "functional" method. The return value | |
| 23 * of |arr.sort()| and |arr| are the same object. | |
| 24 * | |
| 25 * If |arr| is an empty array, the return value of |arr.sort()| should be | |
| 26 * an empty array, not the value |undefined| as was occurring in bug 178722. | |
| 27 * | |
