How would you answer an interview scenario involving routing and code splitting in React?

For an interview scenario involving routing and code splitting, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. Client-side routing maps URLs to React views without full page reloads, while code splitting loads route or feature bundles only when they are needed. In this scenario, if an admin dashboard is large and rarely used, lazy-load the admin route so normal visitors do not download that bundle during the initial page load. For production, give important screens stable URLs, lazy-load large route-level features, provide loading and error states, and ensure direct navigation to a route works in production hosting. I would then explain the main alternatives and tradeoffs, identify likely failure modes, and describe how I would validate the solution through testing, observability, security controls, and recovery or rollback planning.
