Jquery display variable function

I had a friend cook up a variable function for a client site.
I would need to show the var func id “street”, “city”, “dateStart” etc

Is there an easy way to do this with custom code?

This is the script

var item = "";

function deepCopy(src) {
  street = "";
  city = "";
  country = "";
  dateStart = "";
  dateEnd = "";
  timeStart = "";
  timeEnd = "";
  let target = Array.isArray(src) ? [] : {};
  for (let prop in src) {
    let value = src[prop];
    if (value && typeof value === 'object' && prop != 'date') {
      target[prop] = deepCopy(value);

    } else {
      if (prop == "place") {
        locationArr = value.split(",");
        if (locationArr.length > 2) {
          street = locationArr[0];
          city = locationArr[1];
          country = locationArr[2];
        }
        target["Street"] = street;
        target["City"] = city;
        target["Country"] = country;
      }
      if (prop == "date") {
        if (typeof value==='object') {
          dateStart = value[0];
          tempVal = value[0].split(" ");
          if (tempVal.length > 1) {
            dateStart = tempVal[0];
            timeStart = tempVal[1];
          } else {
            dateStart = value[0];
            timeStart = "";
          }
          tempVal = value[0].split(" ");
          if (tempVal.length > 1) {
            dateEnd = tempVal[0];
            timeEnd = tempVal[1];
          } else {
            dateEnd = value[1];
            timeEnd = "";
          }
        }
        target["DateStart"] = dateStart;
        target["TimeStart"] = timeStart;
        target["DateEnd"] = dateEnd;
        target["TimeEnd"] = timeEnd;
      }

      target[prop] = value;
    }
  }
  return target;
}

$.ajax({
  dataType: "json",
  url: "https://franconia-karlsruhe.corpshaus2.de/api/v1/open_events.json",
  async: false,
  success: function(data) {
      item = deepCopy(data);
  }
});
console.log(deepCopy(item));

End result would be something like this
