Json

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is based on a subset of the JavaScript programming language and is often used to transmit data between a server and a web application, as an alternative to XML.

JSON data is represented as a collection of key-value pairs, where each key is a string and each value can be a string, number, boolean, null, array or another JSON object. Keys are always surrounded by double quotes and values can be either in double quotes or not, depending on their type.

JSON is widely used in modern web development, due to its simplicity, compact size, and ability to be easily processed by JavaScript.
