Answer 1

You can try this

function convertDateObj(hhmmss){
	let obj = new Date();//creates a Date Object using the clients current time

    let [hours,minutes,seconds] = hhmmss.split(':'); 

    obj.setHours(+hours); // set the hours, using implicit type coercion
    obj.setMinutes(minutes); //you can pass Number or String, it doesn't really matter
    obj.setSeconds(seconds);
    return obj;
}

let elements =[
  {
    "id": 1,
    "date": "02:01:02"
  },
  {
    "id": 2,
    "date": "01:01:01"
  },
  {
    "id": 3,
    "date": "03:01:01"
  },
  {
    "id": 4,
    "date": "04:01:01"
  }
 ]; 

elements.sort((a, b) => convertDateObj(a.date) - convertDateObj(b.date)); // Ascending order

elements.sort((a, b) => convertDateObj(b.date) - convertDateObj(a.date)); // Descending order
