JS associative object with duplicate names

Question

ok, so I have an object like:

var myobject = {
   \"field_1\": \"lorem ipsum\",
   \"field_2\": 1,
   \"field_2\": 2,
   \"field_2\": 6
};

Answer 1

It is not possible.

The resulting object does only contain 2 elements, the first and second field_2 elements are lost on creation.
