Here's a Hint

Begin by listing the core functionalities of a collaborative editor: real-time editing, multiple user collaboration, version control, formatting tools, etc. Discuss the architecture, focusing on the real-time aspect. Describe the data model, how changes are broadcasted to other users in real-time, and how conflicts are resolved. Consider diving into topics like operational transformation or conflict-free replicated data types (crdts) if you're familiar. Address scalability, ensuring multiple users can work on a document without performance issues. Consider security, ensuring that only authorized users can access and edit documents. As you conclude, discuss usability, ensuring a smooth and intuitive user experience. This question tests your understanding of complex system design, synchronization challenges, and user experience considerations.
