Answer 1

1) You can't sort objects. The order of the object's keys is arbitrary.

2) If you want to sort an array by date (and they are already date obects), do the following:

array.sort ( function (date1, date2){
     return date1 - date2
});

If you first need to convert them to date objects, do the following (following the data structure according to your comment below):

array.sort ( function (a, b){
       return new Date(a.pubDate) - new Date(b.pubDate);
});
