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 ...
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 ...
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]
In software engineering, the adapter pattern is a software design pattern (also known as wrapper, an alternative naming shared with the decorator pattern) that allows the interface of an existing class to be used as another interface. [1]
Join YouTube star Bernadette Banner in Hand Sewing Basics: Work Wonders with Fabric, Needle & Thread. This course covers everything from threading a needle to stitching fabric and sewing on buttons.
In object-oriented programming, the iterator pattern is a design pattern in which an iterator is used to traverse a container and access the container's elements. The iterator pattern decouples algorithms from containers; in some cases, algorithms are necessarily container-specific and thus cannot be decoupled.
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
