JSON (JavaScript Object Notation) and its features

JavaScript Object Notation (JSON) is a lightweight computer data interchange format. It is a text-based, human-readable format for representing simple data structures and associative arrays. The JSON format is specified in RFC 4627. The official Internet media type for JSON is application/json. The JSON file extension is .json. The JSON format is often used for transmitting structured data over a network connection in a process called serialization. Its main application is in Ajax web application programming, where it serves as an alternative to the traditional use of the XML format. Although JSON was based on a subset of the JavaScript programming language and is commonly used with that language, it is considered to be a language-independent data format. Code for parsing and generating JSON data is readily available for a large variety of programming languages. The json.org website provides a comprehensive listing of existing JSON bindings, organized by language.
