Name: JavaScript Notation Object (JSON) Description: Functionally equivalent to a subset of Javascript (but with a slightly different syntax). Data is described in JSON as collections of name-value pairs, where a value can be null, a text string, a number, a boolean, a collection of name-value pairs, or an array of values. The data thus has a recursively nested structure. Source/URL: Refer to: https://www.json.org/json-en.html.
