var person1 = 
    {
      name : 'test1',
      age: 27,
      geschlecht: 'm'
    };

var person2 = 
    {
      name : 'test2',
      age: 80,
      geschlecht: 'm'
    };

var person3 = 
    {
      name : 'test3',
      age: 70,
      geschlecht: 'm'
    };

var persons = [person1, person2, person3];

function sortPersons(items){
  return items.sort(function (a, b) {
    if (a.age > b.age)
      return 1;
    if (a.age < b.age)
      return -1;
    return 0;
});
}

//Alternative Variante fürs Sortieren

//function sortPersons(items) {
//  return items.sort(function(a, b) {
//     return a.age - b.age;
//  });
//}

function logPerson(person) {
  console.log(person);
}

var sortedPersons = sortPersons(persons);

//Alternative Variante fürs Traversieren

//for(var i = 0; i < 3; i++){
//    logPerson(persons[i]);
//}

for(var i in persons) {
  logPerson(persons[i]);
}
