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 .
Transformation Priority Premise (TPP) is a programming approach developed by Robert C. Martin (Uncle Bob) as a refinement to make the process of test-driven development (TDD) easier and more effective for a computer programmer.
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.
In programming, the strangler fig pattern or strangler pattern is an architectural pattern that involves wrapping old code, with the intent of redirecting it to newer code or to log uses of the old code.
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 smells.
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 ...
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.
Code cleanup can also refer to the removal of all computer programming from source code, or the act of removing temporary files after a program has finished executing.. For instance, in a web browser such as Chrome browser or Maxthon, code must be written in order to clean up files such as cookies and storage. [6]
