Say it like this
- We need to refactor this before we ship it.
- That function is a mess—let's refactor it.
- I'm refactoring the database queries for better performance.
- This deserves a refactor to improve readability.
Use it at work
Proposing
- Let's refactor this before we add new features.
- I'd like a day to refactor the auth code.
Code review
- This PR mixes a refactor with a new feature. Can you split it?
- Nice refactor. Much easier to read.
Being careful
- A refactor shouldn't change behavior.
- Let's add tests before we refactor.
Don't say this
Refactoring does not fix bugs; fixing means making broken code work. Use fix for bugs and refactor for code quality.
Don't mix it up
| Term | What it is | Who writes or uses it | When |
|---|---|---|---|
| refactor | Improve code without changing behavior | Developers | Ongoing |
| rewrite | Build it again from scratch | Developers | Rarely |

1. Your code review feedback suggests improving the code structure. Which phrasing is most natural in tech?
2. The database queries are slow, so we decided to _______ them for better performance.
3. Which sentence uses refactor incorrectly?
4. Rewrite this using refactor: We need to make this code cleaner and easier to understand before we add new features.

Real examples(3)
- in a standup
"I spent yesterday refactoring the authentication logic so it's easier for new team members to understand."
- in a code review
"This code works, but we should refactor it to follow our naming conventions and reduce duplication."
- in a team meeting
"We allocated two sprints to refactor the legacy payment system before building the new billing features."
More mistakes(2)
Handle with care. Do not confuse refactoring (improving code structure) with fixing bugs (making broken code work). Refactoring assumes the code already works but needs to be cleaner or more efficient.
- ✕Let us refactor the app to add push notifications.✓Let's refactor the notification service, then add push notifications.
Refactoring improves existing code structure but does not add new features. Adding push notifications is a new feature, not a refactor.
- ✕I refactored the codebase yesterday.✓I refactored the authentication module yesterday.
Refactoring specific parts is more precise and helpful than saying you refactored an entire codebase. Be specific about what you refactored.
Other forms(5)
- refactor verb (base form)
"We should refactor this function."
- refactoring verb (present continuous)
"I am refactoring the database queries right now."
- refactored verb (past tense)
"The team refactored the codebase last month."
- refactor noun
"This refactor will take about three days."
- refactoring noun
"Refactoring is essential for maintaining code quality."
Often used with(5)
- refactor for · Used to indicate the purpose: refactor for readability, refactor for performance, refactor for maintainability.
- refactor into · Used when breaking code into smaller parts: refactor into smaller functions, refactor into microservices.
- refactor before · Common phrase indicating timing: refactor before shipping, refactor before adding features.
- large refactor · Describes a significant restructuring: We are planning a large refactor of the authentication system.
- small refactor · Describes minor improvements: This is just a small refactor to clean up the code.
Similar words(4)
- restructure · More formal and general term; refactor is specific to code.
- rewrite · Suggests writing code from scratch; refactor means improving existing code.
- reorganize · More general; refactor is specific to code quality improvements.
- clean up · More casual; refactor is the technical term used in professional settings.

Questions(5)
- What is the difference between refactoring and fixing a bug?
- Refactoring improves code structure and readability without changing functionality. Fixing a bug makes broken code work correctly. You refactor working code; you fix broken code. For example, renaming variables for clarity is refactoring, but making a failing test pass is fixing.
- Why do developers spend time refactoring if it does not add new features?
- Refactoring reduces technical debt and makes code easier to maintain, test, and extend. Code that is clean and well-organized is faster to work with, less prone to bugs, and easier for new team members to understand. In the long term, regular refactoring saves development time and reduces production issues.
- How do you use refactor in a sentence at work?
- Common sentences include: We should refactor this module before adding the new feature. I am refactoring the authentication logic. Can we schedule time to refactor the database queries? This code would benefit from a refactor.
- Is refactor formal or informal?
- Refactor is neutral and professional. It is used in formal code reviews, team meetings, and documentation, as well as casual conversations between developers. It is the standard technical term in the industry.
- Can refactoring change how the software works?
- No. By definition, refactoring improves code structure without changing behavior. The software should work exactly the same way after refactoring. If you are changing functionality, you are adding features or fixing bugs, not refactoring.
