Create a real-time collaborative code editor that allows multiple users to edit the same document simultaneously. The editor should highlight syntax for at least three different programming languages and include features such as conflict resolution, version control, and chat functionality for communication among users.

Requirements:

1. Implement operational transformation (OT) or conflict-free replicated data type (CRDT) algorithms to handle concurrent edits without conflicts.
2. Design a syntax highlighting engine that supports JavaScript, Python, and Java.
3. Develop a version control system to track changes, revert to previous versions, and merge edits from different users.
4. Create a chat system integrated into the editor for real-time communication.
5. Ensure low-latency updates to provide a seamless user experience.
6. Provide authentication and authorization mechanisms to secure user sessions and documents.
