JSON

JSON is a data transmission standard, also known as: JavaScript Object Notation.

The JSON documentation is managed by ECMA International, and was last updated in 2017.

JSON stands for JavaScript Object Notation. It is a lightweight, human-readable data format used for storing and transporting data. It is the primary alternative to XML for transmitting information between a server and a web application.

JSON’s syntax is derived from JavaScript object literal notation, making it familiar to developers.

It uses key-value pairs and ordered lists of values, which are easy for machines to parse and generate. The structure is simple and clean, consisting of curly braces {} for objects and square brackets [] for arrays. This makes JSON more concise than XML and less prone to errors.

Its simplicity and native compatibility with JavaScript have made it the dominant format for APIs and web services.

A simple JSON file may look like this:

{
    "type": "book",
    "title": "War of the Worlds",
    "author": "HG Wells",
    "price": 15,
}
