Refactor
To refactor is to clean up and reorganize existing code without changing what the app actually does.
Think of it like
Tidying and reorganizing a closet. Same clothes, just easier to find and nicer to use.
Example
“Refactor this to be cleaner” is a common AI prompt. Done right, the app behaves exactly the same, just with neater code.
Why it matters
Beginners fear refactoring will break working features. It should not; if it does, that is a bug, not the point of refactoring.
