State Management

State management in this app is handled using React's Context API. The ContextProvider component wraps the main application and provides state variables and functions to manage themes, country data, search input, and filter options.

Routing

Routing is handled using react-router-dom. The app has several routes defined in main.jsx using the createBrowserRouter and createRoutesFromElements methods.

Routes

• /Where-in-the-world/: Home page displaying all countries.
• /Where-in-the-world/filter/:region: Displays countries filtered by region.
• /Where-in-the-world/country/:countryName: Displays detailed information about a specific country.

Infinite Scroll

Infinite scrolling is implemented using the react-infinite-scroll-component library in the Home.jsx component. This allows users to load more countries as they scroll down the page.
