Refactoring
Changing code structure to improve quality without intentionally changing its behavior.
Example
A large function is split into smaller pieces without changing its behavior.
Why it matters
It makes code easier to maintain and change without deliberately adding new behavior.
You'll hear it
“Let's simplify the structure while keeping the results unchanged.”
Can you control it?
Yes
Yes. You can often use or adjust refactoring directly when the product supports it. The available options and their effect still depend on the tool.
Common questions
- Can refactoring accidentally introduce a bug?
- Yes. A seemingly equivalent rewrite can change behavior in an overlooked case.
- Is adding a new feature refactoring?
- Not by itself. A feature intentionally changes what the software does.
- Can a refactor make future work cheaper?
- Yes. Clearer structure can reduce repeated effort and make mistakes easier to notice.
