How would you use tsconfig.json to enable shorter path aliases?

This tests TypeScript module resolution and compiler configuration. A strong answer explains setting baseUrl to the project root, defining a paths entry mapping @/* to src/*, and clarifying that TypeScript uses this for compile-time resolution only. It should note that build tools like Vite or webpack need their own alias config to resolve those paths at bundle time. A red flag is suggesting file moves or believing tsconfig paths automatically alter runtime behavior without build tool support.
