兴趣爱好Martin Fowler One of the primary goals of refactoring is to eliminate duplicated code, as it can lead to inconsistencies, increase maintenance complexity, and make the codebase more error-prone. Focusing on identifying and extracting common functionality into reusable components, such as abstract classes, interfaces, or utility methods, can greatly improve the maintainability and readability of the code. For example, refactors may accomplish such things as increases in processing speed, sourcing different internal data, or improving security concerns. Another type of refactoring involves streamlining some aspects of the code to make it more efficient, maintainable, or readable. In making program code, software engineers do not work alone but work as a team and other teams continue the previous program and make some changes. Who cares if the computer performs functions that go round and round in executing a feature? It doesn’t matter the software engineer takes a week to refactor and finally from refactoring the software engineer takes an hour to understand it.
