And if you haven’t read it yet, please do before writing another line of code." –David Heinemeier Hansson, Creator of Ruby on Rails, Founder & CTO at Basecamp Fully Revised and Updated—Includes New Refactoring's and Code Examples “Any fool can write code that a computer can understand. Good programmers write code that humans can understand.” –M. Fowler (1999) For more than twenty years, experienced programmers worldwide have relied on Martin Fowler’s Refactoring to improve the design of existing code and to enhance software maintainability, as well as to make existing code easier to understand. This eagerly awaited new edition has been fully updated to reflect crucial changes in the programming landscape. Refactoring, Second Edition, features an updated catalog of refactoring's and includes JavaScript code examples, as well as new functional examples that demonstrate refactoring without classes. Like the original, this edition explains what refactoring is; why you should refactor; how to recognize code that needs refactoring; and how to actually do it successfully, no matter what language you use. Understand the process and general principles of refactoring Quickly apply useful refactorings to make a program easier to comprehend and change Recognize “bad smells” in code that signal opportunities to refactor Explore the refactorings, each with explanations, motivation, mechanics, and simple examples Build solid tests for your refactorings Recognize tradeoffs and obstacles to refactoring Includes free access to the canonical web edition, with even more refactoring resources. (See inside the book for details about how to access the web edition.) Review: Great book. - Wonderful book on refactoring. Review: Absolute must have book for every developer’s library! - Fantastic book and one that should be in every developers personal library. The depth of knowledge and technical precision the author has in regards to refactoring is immense. This book is not a quick read but should be read in its entirety to really take in all that refactoring has to offer. Refactoring has now become part of my everyday programming and development process. There is only one thing I would change about the book and that is for the author to add the completed refactored code for some of the more complex methodologies to the end of each refactoring. Some of the refactoring methodologies can be quite extensive and by adding the completed refactored code to the end may help give a clearer picture of the information the author is imparting to the reader. Other than that this book has taught me so much about refactoring and will be a go to book for the rest of my software development career. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #59,241 in Books ( See Top 100 in Books ) #8 in Object-Oriented Design #11 in Software Testing #35 in Software Development (Books) | | Customer Reviews | 4.7 out of 5 stars 1,212 Reviews | ## Images ![Refactoring: Improving the Design of Existing Code (2nd Edition) (Addison-Wesley Signature Series (Fowler)) - Image 1](https://m.media-amazon.com/images/I/71vEr0oyt-L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great book. *by R***Y on December 13, 2025* Wonderful book on refactoring. ### ⭐⭐⭐⭐⭐ Absolute must have book for every developer’s library! *by J***E on January 3, 2023* Fantastic book and one that should be in every developers personal library.

I'm a Java dev with 6yoe and I still learn from this book. There are some things I knew, some I forgotten or thought about but didn't know a proper name of and some I have never thought of. The language used is Javascript but it's syntax shouldn't be hard to follow. Also, the book quality is high and there are lots of pretty diagrams if it matters for you (it certainly does for me). ## Frequently Bought Together - Refactoring: Improving the Design of Existing Code (2nd Edition) (Addison-Wesley Signature Series (Fowler)) - The Pragmatic Programmer: Your Journey To Mastery, 20th Anniversary Edition (2nd Edition) - Clean Code: A Handbook of Agile Software Craftsmanship --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/83397920-refactoring-improving-the-design-of-existing-code-2nd-edition-addison](https://www.desertcart.com.br/products/83397920-refactoring-improving-the-design-of-existing-code-2nd-edition-addison) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-05-20*
