+JSON in JavaScript

+
+
+JSON is a light-weight, language independent, data interchange format.
+See http://www.JSON.org/
+
+The files in this collection implement JSON encoders/decoders in JavaScript.
+
+JSON became a built-in feature of JavaScript when the ECMAScript Programming
+Language Standard - Fifth Edition was adopted by the ECMA General Assembly
+in December 2009. Most of the files in this collection are for applications
+that are expected to run in obsolete web browsers. For most purposes, json2.js
+is the best choice.
+
+
+json2.js: This file creates a JSON property in the global object, if there
+isn't already one, setting its value to an object containing a stringify
+method and a parse method. The parse method uses the eval method to do the
+parsing, guarding it with several regular expressions to defend against
+accidental code execution hazards. On current browsers, this file does nothing,
+preferring the built-in JSON object. There is no reason to use this file unless
+fate compels you to support IE8, which is something that no one should ever 
+have to do again.
+
+json_parse.js: This file contains an alternative JSON parse function that
+uses recursive descent instead of eval.
+
+json_parse_state.js: This files contains an alternative JSON parse function that
+uses a state machine instead of eval.
+
+cycle.js: This file contains two functions, JSON.decycle and JSON.retrocycle,
+which make it possible to encode cyclical structures and dags in JSON, and to
+then recover them. This is a capability that is not provided by ES5. JSONPath 
+is used to represent the links. [http://GOESSNER.net/articles/JsonPath/]
