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 .
Refactoring refers to a software maintenance activity where source code is modified to improve readability or improve its structure. Software is often refactored to bring it into conformance with a team's stated coding standards after its initial release. Any change that does not alter the behavior of the software can be considered refactoring.
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.
Refactoring is a term well-known in software engineering. It refers to the process of restructuring existing computer code to make it cleaner, more efficient, and easier to understand—all ...
Rule of three ("Three strikes and you refactor") is a code refactoring rule of thumb to decide when similar pieces of code should be refactored to avoid duplication. 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.
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 ...
AntiPatterns: Refactoring Software, Architectures, and Projects in Crisis [1] is a book about anti-patterns: specific repeated practices in software architecture, software design and software project management that initially appear to be beneficial, but ultimately result in bad consequences that outweigh hoped-for advantages.
