Instantiating a javascript object and populating its properties in a single line

Question

Is there a way I can do all of this in a constructor?

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

Answer 1

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

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

var objectInstance = new MyObject(params);

This would be the prototype way, which i prefere over plain object literals when i need more then one instance of the object.
