How to order an array of object during a forEach()?

Question

So, basically I have this array of objects and I need to order them dependently on the value caricoData, which is a date. Problem is, the value is a string and I can't change that due to other interactions with the array that need it to be a string, so what I did is I made a forEach() method to turn each caricoData of each element into a date (DD/MM/YYY). But then I need it to put it back as a string due to it needing to be so. So what I thought was "What if I make it so that before returning it into a string, I make it so the array sorts itself in the making?" Problem is, I don't know how to do it. I've tried with:

  filterDateCheck(array){
     array.sort((a,b) => (a.caricoData > b.caricoData) ? 1 : ((b.caricoData > a.caricoData) ? -1 : 0))
     return array
   }

But it doesn't work, returning Invalid Date as a result. So, how can I do it?

TS:

check.forEach(e => {
  let formattedDate = Utilities.toDateTimeString(e.caricoData)
  let splitDate = formattedDate.split("/")
  let dateObject = new Date(+splitDate[2], +splitDate[1] - 1, +splitDate[0]); 
  // Method goes here? //
  e.caricoData = dateObject.toString();  
});

Array (check) structure:

 export class ResCheck{
  descrizioneIntervento: string;
  destinazioneDescrizione: string;
  fermoLocalita: string;
  caricoData: string;
  veicoloTarga: string; 
  destinazione: string;
}
