Understanding JSON: A Beginner's Guide

Author, TinyTool

JSON (JavaScript Object Notation) has become the de-facto standard for data exchange on the web. It is a lightweight format that is easy for humans to read and write, and easy for machines to parse and generate.

Why JSON?

JSON is preferred over XML for several reasons:

  • Less Verbose: It uses fewer characters than XML.
  • Faster: Parsing JSON is generally faster than parsing XML.
  • Language Independent: Although derived from JavaScript, JSON is supported by almost every programming language.

Basic Structure

JSON is built on two structures:

  1. A collection of name/value pairs (Object).
  2. An ordered list of values (Array).
{
  "name": "TinyTool",
  "features": ["Speed", "Security", "Simplicity"],
  "active": true
}

Tips for Formatting

Always ensure your JSON is valid. Common mistakes include:

  • Trailing commas after the last element.
  • Using single quotes instead of double quotes for keys or string values.
  • Missing colons between keys and values.
