Detailed Description

JavaScript Object Notation or JSON is an open - standard file format that uses human - readable text to transmit data objects consisting of attribute–value pairs and array data types(or any other serializable value).

Class: JSONNode

It is a very common data format used for asynchronous browser–server communication, including as a replacement for XML in some AJAX - style systems.

The JSONNode class serves as a container for data and it's children. Includes options to read and write from streams and files.
