What is the primary value of refactoring code?

Refactoring code primarily aims to improve readability and maintainability, which are essential characteristics of high-quality software. When developers refactor, they restructure existing code without altering its external behavior, making it clearer and easier to follow. This process often involves cleaning up convoluted logic, eliminating duplicate code, and enhancing the overall architecture of the system, all of which facilitate better understanding and modification in the future.

Improved readability means that current and future developers can grasp the code's intent and functionality more easily, which is vital in collaborative environments. When code is maintainable, it can be changed or extended with minimal effort, reducing the likelihood of introducing bugs. Thus, the value derived from refactoring is most clearly aligned with enhancing the code’s clarity and its long-term sustainability in a rapidly evolving development landscape.
