What is Json ?

JavaScript Object Notation is an open standard file format, and data interchange format, that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and array data types.

JSON is a language-independent data format. It was derived from JavaScript, but many modern programming languages include code to generate and parse JSON-format data. The official Internet media type for JSON is application/json. JSON filenames use the extension .json.


Object

An object is an unordered set of name/value pairs. An object begins with { left brace and ends with } right brace. Each name is followed by : colon and the name/value pairs are separated by , comma.
