Is there a way to do all this in the constructor?

  obj = new Object();
  obj.city = "A";
  obj.town = "B";

Why don't you just do this:

var obj = {"city": "A", "town": "B"};

Same:

var obj = {
    city: "a",
    town: "b"
}

source 
function MyObject(params) {
    // Your constructor
    this.init(params);
}

MyObject.prototype = {
    init: function(params) {
        // Your code called by constructor
    }
}

var objectInstance = new MyObject(params);
