Let’s continue the same example to learn some new things about refactoring. Reading is not as good as doing. I learned from the folks at Big
Refactoring remains a much-misunderstood discipline. Even when folks do have unit tests to back their changes, how long does the code stay broken? Let’s return to the idea that refactoring happens in very small steps. No, even smaller than that.
