I can't get this sorted by relevantDate. I need newest date first. Can you please help me? Thanks a lot in anticipation!

publications = [{
    "publicationDate" : "12.05.2022",
    "relevantDate" : "01.06.2022",
    "title" : "Bücher",
    "type" : "allgemein"
  }, {
    "publicationDate" : "04.05.2022",
    "relevantDate" : "21.05.2022",
    "title" : "Videos",
    "type" : "allgemein"
  }, {
    "publicationDate" : "14.04.2022",
    "relevantDate" : "25.05.2022",
    "title" : "Musik",
    "type" : "allgemein"
  }];


     publications.sort(function(a, b){
     return new Date(a.relevantDate) - new Date(b.relevantDate);
     });

  • You need to parse that date manually, just passing it to the `Date` constructor will not be reliable. There are plenty of examples of doing this on SO – Jamiec May 12 '22 at 13:58

    I was in the process of supplying an answer this so that the requester could understand where their issue lay but the question was closed. I will briefly say that the format your dates are arriving in are not one that the Date object constructor understands. I would recommend if you have any control over the API to get the dates sent in a recognised ISO format. Failing that you can string manipulate them into something that the date constructor will accept. Something like this might work, but I would check it works in all cases! `new Date("14.04.2022".split('.').reverse().join())` – Glenn Holland May 12 '22 at 14:03
  • Thank you very much, Glenn! This is great :-) It works: `return new Date(a.relevantDate.split('.').reverse().join()).getTime() - new Date(b.relevantDate.split('.').reverse().join()).getTime();` or just `return new Date(a.relevantDate.split('.').reverse().join()) - new Date(b.relevantDate.split('.').reverse().join());` – user19102478 May 12 '22 at 14:11
