## What it is
An open book by Alex Bespoyasov teaching how to refactor code efficiently, covering topics from naming and duplication to architecture and typing, with examples in JavaScript and TypeScript. It is available online, as PDF, and as Epub in English and Russian with community translations in progress.

## Use cases
- learn how to refactor code
- improve code quality and readability
- find and fix code smells
- reduce coupling and complexity in a codebase
- learn refactoring techniques with JavaScript examples
- understand how to handle side effects and error handling
- prepare for code reviews and legacy code cleanup

## When to choose
- you want a free, practical guide to refactoring with JS/TS examples
- you are a junior or mid-level developer learning clean code practices
- you prefer reading as a web book, PDF, or Epub
- you want language-agnostic refactoring principles applicable beyond JavaScript

## When to avoid
- you need a hands-on refactoring tool or automated codemod rather than a book
- you want deep coverage of languages other than JS/TS
- you need a formally licensed derivative work - the book is CC BY-NC-ND
