Breakdown of the file structure:

 

• The components directory contains individual component folders. Each component has its own folder with separate files for the component's JavaScript logic (ComponentName.js) and CSS styles (ComponentName.css).
• The pages directory contains page-specific components. Each page has its own folder with separate files for the page's JavaScript logic (PageName.js) and CSS styles (PageName.css).
• The App.js file serves as the entry point for the application. It acts as a container component that renders the different pages and components.
• The index.js file is responsible for rendering the App component and mounting it to the root DOM element.
