Design TikTok.

When designing TikTok, focus on the core features that make the platform engaging and user-friendly. Consider the user experience from the moment they open the app: how they discover content, interact with videos, and create their own. Discuss the algorithm for content recommendation, emphasizing how it personalizes the feed based on user behavior. Address the technical aspects of video uploading, editing tools, and social sharing functionalities. Finally, think about scalability and how to handle a growing user base while maintaining performance and responsiveness.
