(JSON) JavaScript Object Notation

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, or between different parts of a web application.

A JSON object is an unordered collection of key-value pairs, where the keys are strings and the values can be any valid JSON data type (such as strings, numbers, objects, arrays, Boolean values, or null). Here's an example of a simple JSON object:


  "name": "John Doe",
  "age": 30,
  "isEmployed": true,
  "hobbies": ["reading", "traveling", "hiking"]

JSON is widely supported by many programming languages, including JavaScript, Python, Ruby, Java, and C#, making it a popular choice for exchanging data between systems.
