## What it is
An open-source, step-by-step tutorial that teaches Test Driven Development (TDD) to complete beginners using JavaScript and QUnit. It is educational content rather than a tool, walking learners from writing their first test to building more reliable code with a test-first workflow.

## Use cases
- learn test driven development from scratch
- tdd tutorial for beginners
- how to write tests before code in javascript
- learn unit testing with qunit
- step-by-step intro to software testing
- beginner guide to writing reliable javascript with tests

## When to choose
- You are a complete beginner who wants a short, hands-on introduction to TDD in JavaScript
- You want a zero-dependency, browser-based tutorial you can finish in roughly 30 minutes
- You prefer learning through guided exercises with runnable starter files and bonus levels

## When to avoid
- You need a testing library or framework to install in production projects rather than educational content
- You already know TDD fundamentals and need advanced coverage of mocking, integration, or end-to-end testing
- You want TDD instruction in a language other than JavaScript
