How would you structure folders and code in a large React project?
Model answer
Group by feature rather than by file type: each feature folder holds its components, hooks, API calls and tests, with a shared folder for common UI and utilities. Keep components small, put data access in hooks, use absolute imports, and enforce boundaries with lint rules.
The exact layout matters less than staying consistent and keeping related code together.
