inspired by the answer given in this post and understanding you just want to get the property-names, not values, you could do it like this. sorry, this uses plain javascript.

function flattenObjectToKeyArray(ob) {
  var toReturn = [];
  for (var prop in ob) {
    if (!ob.hasOwnProperty(prop)) continue;

    if ((typeof ob[prop]) == 'object' && ob[prop] !== null) {
      var flatObject = flattenObjectToKeyArray(ob[prop]);
      for (var idx = 0; idx < flatObject.length; idx++) {
        toReturn.push(prop + '.' + flatObject[idx]);
      }
    } else {
      toReturn.push(prop);
    }
  }
  return toReturn;
}
