You could use $.each() or $.map(), depending on what you want to do with it.

$.map(Persons, function(person) {
    return person.LastName + ", " + person.FirstName;
});
// -> ["Doe, John", "Appleseed, Marc", …]

You can use $.each() to iterate through the array.

$.each(test.Persons, function(index){
    alert(this.FirstName);
    alert(this.LastName);
});

See a working demo

You can use JavaScript syntax for array:

for(var i in test.Persons) {
    alert(test.Persons[i].FirstName + " " + test.Persons[i].LastName);
}

Using jQuery for that is a little overkill imho.

Array.forEach:

test.Persons.forEach(function(person) {
  alert(person.FirstName + " " + person.LastName);
});

or simply by index:

alert(test.Persons[0].FirstName + " " + test.Persons[0].LastName);
