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 .
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.
Thus, a code smell is a driver for refactoring. Factors such as the understandability of code, how easy it is to be modified, the ease in which it can be enhanced to support functional changes, the code's ability to be reused in different settings, how testable the code is, and code reliability are factors that can be used to identify code ...
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.

Code cleanup refers to the act of writing so that it cleans up leftover and other unwanted materials from memory and the filesystem. It is sometimes treated as a synonym of refactoring code, which involves making the source code itself easier to understand, maintain, and modify.
This beckons as another opportunity for refactoring to be used in order to improve the quality of the code. Refactoring to eliminate data clumps does not need to be done by hand. Many modern fully featured IDEs have functionality (often labeled as "Extract Class") that is capable of performing this refactoring automatically or nearly so. This ...
A decomposition paradigm in computer programming is a strategy for organizing a program as a number of parts, and usually implies a specific way to organize a program text.
