Answer 1

Try https://github.com/douglascrockford/JSON-js/blob/master/json2.js. There is a parse function which will parse your string into a javascript object safely.

To do the actual parsing, you can use json2.js or JQuery's $.parseJSON() method. Those will create a javascript object that directly resembles the JSON you sent across.

Since Javascript is a script language, you won't be thinking in terms of "polymorphism" anymore, but you should be able to evaluate properties on the objects (without caring what "type" of object they are) like so:

var obj = $.parseJSON(json);
var firstAnimalName = obj.Animals[0].Name;
