Why is refactoring so hard?
Why is refactoring so hard?
Refactoring is difficult because many, if not most, programmers do not know what the end result should be. They have really never seen well written code and have been taught since writing their first line of code that if it compiles and runs, that is enough. Refactoring is unnecessary.

When should refactoring not be done?
One should not start refactoring unless he has a clear purpose in mind. Once the purpose has been accomplished, one is done. There is probably not an explicit 10 point check list to tell you when you are done, but most people can determine if they are being productive or just playing.
Does refactoring improve performance?
Refactoring may lessen performance, but the change may be negligible. You need to balance the change in the maintainability of the code vs. the change in its performance.
What is the best approach to ensure that a code fix doesn’t break?
Refactoring your code makes it easier to read and maintain. Refactoring doesn’t change the external functionality of your code; it changes the way the code achieves that functionality.
What is ravioli code?
Ravioli code is metaphor for small, self-contained classes of code, which resemble individual pieces of pasta. Ravioli code emphasizes a component-based code style and encourages the separation of concerns. This practice is a good start for readable, maintainable code, as a ravioli codebase is well-structured.
What is a bad code smell?
Code smells are usually not bugs; they are not technically incorrect and do not prevent the program from functioning. Instead, they indicate weaknesses in design that may slow down development or increase the risk of bugs or failures in the future.
