What kind of code is worth rewriting?

Determining whether a piece of code is worth rewriting depends on several factors, including the code’s maintainability, readability, performance, scalability, and adherence to best practices. Let’s look at some situations where code may be worth rewriting.

Smelly code is often an indication that code needs to be rewritten. These are signs of poor design or implementation, such as long methods, large classes, duplicated code, or poor naming conventions. Addressing these code smells can improve the overall quality of the code base and make it easier to maintain in the long run.

Code that exhibits low cohesion or high coupling might be worth rewriting. Low cohesion means that the elements within a module or class are not closely related, and the module or class has too many responsibilities. High coupling refers to a high degree of dependency between modules or classes, making the code harder to maintain and modify. Refactoring...
