Overview
JSON stands for JavaScript Object Notation. It is a standardized text format for serialization of structured data. It is described by RFC 4627 and RFC 7159. What is the relationship?.
It defines a small set of formatting rules for portable representation of simple data structures such as key-value pair collections, lists, etc. JSON is also an internet media type, a text based content type that can be directly interpreted by JavaScript. It is the preferred exchange format for JavaScript-based web applications. The MIME media type for JSON is "application/json".
JSON uses attribute-value pairs.
JSON has a few advantages as a serialization format: there are serialization-deserialization libraries in most programming languages, all modern browsers support it, and it is human-readable. There are disadvantages as well: JSON is not size-efficient, and the serialization-deserialization speed is not among the best. Other serialization protocols are faster.
