JSON or JavaScript Object Notation is a lightweight open standard format that is used for interchanging data. JSON is widely used for storing and transmitting data objects that consist of array data types and attribute-value pairs. The reason behind its popularity is the utilization of human-readable text in it, which makes it easier for humans to read and write the codes.

JSON is serving as a replacement of XML, which was used as a primary data format for interchanging data. But due to the fact that JSON is more lightweight, XML was eliminated, and JSON took its place. The most common use of JSON is the transmission and serializing of the structured data over a network connection. The JSON format is also used to share data amongst a server and web applications. Many programmers use JSON alongside modern programming languages.

The example of a JSON to transmit information about a book’s writer, language, and version is as follows:


"book": [



"language": "English",

"version": "second",

“writer”: “Charles Dickens”




"chapters": "16",

"version": "second",

“writer”: “Garry Thompson”
