Answer 1

You can do something like this

var elements = {
  element: {
    date: {
      day: 'Monday'
    },
    example: {
      abc: 'hii'
    }
  }
};

function getObjectByStringIdentifier(stringId) {
  stringId = stringId.split('.');
  // split string using `.`
  var res = elements;
  // define res as object
  for (var i = 0; i < stringId.length; i++)
  // iterate over array
    res = res[stringId[i]]
    // update res as inner object value
  return res;
  // return result
}

console.log(getObjectByStringIdentifier("element.date.day"));
console.log(getObjectByStringIdentifier("element.example.abc"));
