I'll create a simplified YouTube clone using React and Next.js. This clone will include a video player, a list of recommended videos, a video description, comments, and a search bar. Let's break it down into components and implement the basic structure.

Let's start by creating the main components:

This YouTube clone implementation includes the following features:

1. A responsive layout with a header, main content area, and sidebar for recommended videos.
2. A header with a YouTube logo, search bar, and sign-in button.
3. A video player component (using a placeholder video).
4. A video description section with title, channel information, and interaction buttons.
5. A comment section with sample comments and a form to add new comments.
6. A list of recommended videos in the sidebar.

The components use shadcn/ui for styling and Lucide React icons for a clean, modern look. The layout is responsive and will adjust for different screen sizes.

To further enhance this YouTube clone, you could:

1. Implement actual video playback functionality.
2. Add state management (e.g., using React Context or a state management library) to handle video data, comments, and user interactions.
3. Implement real search functionality and dynamic video loading.
4. Add user authentication for commenting and liking videos.
5. Implement a backend API to fetch real video data, comments, and handle user interactions.
