JavaScript Object Notation

JavaScript Object Notation, or JSON, is a lightweight data format used to store and exchange information. It resembles how we write objects in JavaScript, using key-value pairs similar to a dictionary. For example, a JSON object might represent a person with keys like "name" and "age", showing values like "Alice" and 30. JSON is easy for humans to read and write, and simple for computers to parse and generate. It's widely used in web applications to send data between a server and a client, making it a cornerstone of modern web development.
