Turn spaghetti code into modular, maintainable functions without changing the original behavior.
Steps
- Open Claude or ChatGPT in your browser.
- Copy the legacy code you want to refactor from your code editor.
- Paste the prompt template into the AI chat window.
- Replace {language} with your programming language (e.g., Python, JavaScript) and {code} with your copied legacy code.
- Press Enter and wait for the AI to generate the refactored code.
- Review the AI's output to ensure the logic matches your original code.
- Copy the refactored code from the chat, paste it back into your editor, and run your existing tests to verify nothing broke.
