Basic JSON Structure

{
  "string": "Hello, World!",
  "number": 42,
  "boolean": true,
  "null": null,
  "array": [1, 2, 3, 4, 5],
  "object": {
    "name": "John Doe",
    "age": 30,
    "email": "john@example.com"
  }
}

JSON supports six data types: strings, numbers, booleans, null, arrays, and objects.

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?

  • Language Independent: JSON can be used with any programming language
  • Human Readable: Easy to read and understand
  • Compact: Minimal syntax overhead
  • Widely Supported: Native support in most programming languages
