In computer programming and software design, code refactoring is the process of restructuring existing source code—changing the factoring—without changing its external behavior. Refactoring is intended to improve the design, structure, and/or implementation of the software (its non-functional attributes), while preserving its functionality .

It states that two instances of similar code do not require refactoring, but when similar code is used three times, it should be extracted into a new procedure. The rule was popularised by Martin Fowler in Refactoring [1] and attributed to Don Roberts. Duplication is considered a bad practice in programming because it makes the code harder to ...

Martin Fowler (18 December 1963) is a British software developer, [2] author and international public speaker on software development, specialising in object-oriented analysis and design, UML, patterns, and agile software development methodologies, including extreme programming. His 1999 book Refactoring popularised the practice of code ...
Refactoring is a means of addressing the problem of software rot. It is described as the process of rewriting existing code to improve its structure without affecting its external behaviour. [9] This includes removing dead code and rewriting sections that have been modified extensively and no longer work efficiently. Care must be taken not to ...
Code Complete is a software development book, written by Steve McConnell and published in 1993 by Microsoft Press, encouraging developers to continue past code-and-fix programming and the big design up front and waterfall models. It is also a compendium of software construction techniques, which include techniques from naming variables to ...
In computer programming, a design smell is a structure in a design that indicates a violation of fundamental design principles, and which can negatively impact the project's quality. [1] The origin of the term can be traced to the term "code smell" which was featured in the book Refactoring: Improving the Design of Existing Code by Martin ...
