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