Sort array by date - javascript

Question

I want to sort an array of objects by date, but the problem is their date is in this format - 2014-07-17T13:49:12.767Z.

Here an example of one object in this array

{
  id: 578,
  creationDate: "2014-07-16T20:56:04.710Z",
  creationUser: "FCOUT",
  modificationDate: "2014-07-17T13:49:12.767Z",
  modificationUser: "FCOUT",
  name: "Regra Filipe",
  description: "Teste",
  type: "Message",
  regulation: null,
  structure: 1,
  deleted: false,
}

I have to sort them by modification date or creation date!

Why is it a problem that the dates are in UTC format? Doesn't that make things easier? Just use a normal sort: http://www.w3schools.com/jsref/jsref_sort.asp — Søren Ullidtz, Jul 17 '14 at 18:37
What exactly makes you think that the date format is a problem? Did you even try anything? — Patrick Q, Jul 17 '14 at 18:38

Just write a sort function as given here. In your case the compare function will just be comparing two strings , which in the date format you have mentioned should work out of the box.

ie you can compare the two dates as strings.

Mozilla sorting documentation

use the compare function

function(a, b) {
    if (a.creationDate < b.creationDate) { return -1; }
    if (a.creationDate > b.creationDate) { return 1; }
    return 0;
}

Your date format allows the creationDate strings to just be compared lexicographically
