JSON Basics
What is JSON?
JSON (JavaScript Object Notation) is a lightweight, text-based data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is language-independent and widely used for transmitting data between a server and web application. JSON represents data as key-value pairs and arrays, making it perfect for structured data. The format supports strings, numbers, booleans, null values, objects, and arrays. JSON has become the de facto standard for web APIs, configuration files, and data storage due to its simplicity, flexibility, and broad support across programming languages.
