JSON Cheatsheet

Overview

JSON (JavaScript Object Notation) is a lightweight data interchange format.
It is often used for APIs, configuration files, and data exchange between languages.
JSON files use a .json file extension.

Basic Syntax

Data is represented as key-value pairs, where the key is a string and the value can be a string, number, boolean, null, array, or object.
Keys and strings are enclosed in double quotes.
Arrays are enclosed in square brackets and separated by commas.
Objects are enclosed in curly braces and contain key-value pairs separated by commas.

Example

// Example JSON file
{
  "name": "John Smith",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "Anytown",
    "state": "CA",
    "zip": "12345"
  },
  "skills": ["Ruby", "Python", "JavaScript"]
}

Data Types

Strings: enclosed in double quotes
Numbers: integers or floating-point numbers
Booleans: true or false
Null: null
Arrays: ordered collections of data
Objects: unordered collections of key-value pairs

Advanced Syntax

Comments are not allowed in JSON.
Multiline strings can be represented using escape characters (\n for a new line).
JSON can be pretty-printed to make it more human-readable.
