Section 1
The big idea
Refactoring means improving code without changing what it does. AI is great at suggesting cleaner versions — but you have to test after every change or you'll break something silently.
Some examples
- Paste a 50-line function and ask AI to split it into three smaller ones.
- Ask AI to rename variables to be clearer without changing logic.
- Have AI suggest a better folder structure for your project.
- Run your tests after every refactor — even small ones.
Try it!
Find your messiest old function. Ask AI for a cleaner version. Diff the two and only keep changes you understand.
