Sort date in Javascript

Question

I have retrieve from ajax query a news feed. In this object, there is a date in this format :

Wed, 22 May 2013 08:00:00 GMT

I would like to sort all objects by date. Is it possible to do this using Javascript ?

UPDATE

Using this piece of code it works fine !

array.sort(function(a,b){
var c = new Date(a.date);
var d = new Date(b.date);
return c-d;
});

What does your current code that isn't working look like? What have you tried? — h2ooooooo

Sure is this possible. How would you like to have it sorted? By weekday, by timezone or by month? :-D — Christoph

What if you put "javascript array sort" to google.com and see what happens? — zerkms

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);
});

In fact, i have an array of news Object which contains the following keys : title, description, url and pubdate. I would like to sort my array by date.

@pxrb66 Then you can compare the pubdates of your array elements function(a,b){new Date(a.pubDate)-new Date(b-pubDate)}.

You may also use a underscore/lodash sortBy

Here's using underscore js to sort date:

 var log = [{date: '2016-01-16T05:23:38+00:00', other: 'sample'}, 
            {date: '2016-01-13T05:23:38+00:00',other: 'sample'}, 
            {date: '2016-01-15T11:23:38+00:00', other: 'sample'}];

  console.log(_.sortBy(log, 'date'));

sorting dates ascending or descending
times = ["01-09-2013", "01-09-2013", "27-08-2013", "27-08-2013", "28-08-2013", "28-08-2013", "28-08-2013", "28-08-2013", "29-08-2013", "29-08-2013", "30-08-2013", "30-08-2013", "31-08-2013", "31-08-2013"]
function dmyOrdA(a,b){ return myDate(a) - myDate(b);}
function dmyOrdD(a,b){ return myDate(b) - myDate(a);}
function myDate(s){var a=s.split(/-|\//); return new Date(a[2],a[1]-1,a[0]);}

times.sort(dmyOrdA);
console.log(times)
