Answer 1

A working version with optional time values.

var obj = [{
    "id": 1,
    "dateOfBirth": "1.7.1990"
  },
  {
    "id": 4,
    "dateOfBirth": "4.02.1976 14:37"
  }, {
    "id": 2,
    "dateOfBirth": "28.10.1950 2:15"
  }
];

console.log(
  obj.sort(function(a, b) {
    return parseDate(a.dateOfBirth) -
      parseDate(b.dateOfBirth);
  })
);

function parseDate(str) {
  var tokens = str.split(/\D/);
  while (tokens.length < 5)
    tokens.push(0);

  return new Date(tokens[2], tokens[1]-1, tokens[0], tokens[3]||0, tokens[4]||0);
}
