What Is JSON?

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.

Why Use JSON?

JSON has become the de facto standard for APIs and web services. Before JSON, XML was heavily used, but JSON's simpler syntax and direct mapping to JavaScript objects made it the clear winner for modern web development.

Example of JSON:

{
  "name": "John Doe",
  "age": 30,
  "isDeveloper": true,
  "skills": ["JavaScript", "React", "Node.js"]
}

Key Characteristics

1. Text-based: JSON is entirely text-based, making it easy to transfer over HTTP.
2. Language Independent: While derived from JavaScript, JSON is supported by almost every programming language (Python, Java, C#, Go, etc.).
3. Structured: Data is organized in key-value pairs (objects) and ordered lists (arrays).
