What is JSON?

JSON (JavaScript Object Notation) is a lightweight data format used to store and exchange information between systems. It uses human-readable text with key-value pairs and arrays, making it easy for both people and computers to understand. JSON has become the standard format for web APIs, configuration files, and data storage because of its simplicity and universal support across programming languages.
