Javascript deep copying object [duplicate]

by

I’ve found that the best way to go is this:

http://andrewdupont.net/2009/08/28/deep-extending-objects-in-javascript/

Object.deepExtend = function(destination, source) {
  for (var property in source) {
    if (typeof source[property] === "object" &&
     source[property] !== null ) {
      destination[property] = destination[property] || {};
      arguments.callee(destination[property], source[property]);
    } else {
      destination[property] = source[property];
    }
  }
  return destination;
};


Object.extend(destination, source);

What about this?

    function clone(destination, source) {
        for (var property in source) {
            if (typeof source[property] === "object" && source[property] !== null && destination[property]) { 
                clone(destination[property], source[property]);
            } else {
                destination[property] = source[property];
            }
        }
    };
