Context A UI component must display different content depending on whether a user is logged in. The Problem The team is duplicating entire component trees and toggling CSS classes via JavaScript, rather than using React's conditional rendering patterns. Constraints Use a boolean state variable isLoggedIn. Render a welcome message when true, and a login prompt when false. Toggle the state with a button click. Expected Deliverable A React component demonstrating conditional rendering using a ternary operator or short-circuit evaluation based on a state variable.
