## What it is
An educational guide that teaches software architecture through three 'ilities': readability, reusability, and refactorability. It uses a simple JavaScript shopping cart example built with React and Redux, showing Bad vs. Good code versions at each step.

## Use cases
- learn software architecture principles
- improve code readability in JavaScript
- understand how to write reusable code
- learn refactoring techniques with React and Redux examples
- find a mental model for evaluating code quality
- teach junior developers software design

## When to choose
- you are a beginner or intermediate developer learning software architecture
- you work with JavaScript, React, or Redux and want concrete before/after examples
- you want a hierarchical framework for thinking about code quality

## When to avoid
- you need a framework or library to use in production
- you want language-agnostic or non-JavaScript architecture guidance
- you need comprehensive, formal architecture documentation

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools, documentation
- domain: developer-tools, web-development, tutorials
- platform: -
- tags: software-architecture, code-quality, readability, reusability, refactoring, react, redux, guide, javascript, web-server
