JSON Tutorial

JSON (JavaScript Object Notation) is a lightweight format for storing and transporting data. It is widely used in web development to exchange data between a client and a server.

What is JSON?

JSON is a text-based data format that represents structured data using key-value pairs. It is commonly used for data transmission in web applications and APIs.

JSON Syntax

• Data is stored in **key-value pairs**.
• Keys are always strings enclosed in double quotes (**" "**).
• Values can be strings, numbers, booleans, arrays, objects, or null.
• Data is separated by **commas**.
• Objects are enclosed in **curly braces **.
• Arrays are enclosed in **square brackets [ ]**.

JSON Example:

{
  "name": "John Doe",
  "age": 30,
  "email": "johndoe@example.com",
  "isSubscribed": true,
  "hobbies": ["reading", "gaming", "coding"],
  "address": {
    "street": "123 Main St",
    "city": "New York",
    "zip": "10001"
  }
}

Why Use JSON?

• Lightweight: Uses minimal formatting compared to XML.
• Easy to Read & Write: Uses simple key-value pairs.
• Language-Independent: Compatible with almost every programming language.
• Fast Processing: Can be quickly parsed and generated.
• Widely Used: Standard format for web APIs and data storage.
