Refactoring : Improving the Design of Existing Code

About the book

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 Refactorings 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 refactorings and includes JavaScript code examples, as well as new functional examples that demonstrate refactoring without classes.

Kent Beck consistently challenges software engineering dogma, promoting ideas like patterns, test-driven development, and Extreme Programming. Currently affiliated with Three Rivers Institute and Agitar Software, he is the author of many Addison-Wesley titles. John Brant and Don Roberts are the authors of the Refactoring Browser for Smalltalk, which is found at http://st-www.cs.uiuc.edu/~brant/RefactoringBrowser/. They are also consultants who have studied both the practical and theoretical aspects of refactoring for six years. William Opdyke's doctoral research on refactoring object-oriented frameworks at the University of Illinois led to the first major publication on this topic. He is currently a Distinguished Member of Technical Staff at Lucent Technologies/Bell Laboratories.
