Review Summary
I am approving your solution, great work! The core logic for moving and renaming files is solid and meets all the functional requirements. You've correctly handled the different scenarios for destination paths.
For future projects, consider these two improvements to make your command-line tools more robust. First, it's a standard convention to exit with a non-zero status code on error, like process.exit(1), to signal failure to scripts. Second, providing consistent error messages for similar issues, such as a non-existent destination directory, makes the tool more user-friendly. These are not blockers for this task, but are important practices for professional development. Keep up the great work!

While this works, it's a standard convention for command-line applications to exit with a non-zero status code (e.g., process.exit(1)) to signal that an error has occurred. This is helpful for scripting and automation where the exit code is checked to determine success or failure.

This error message is a bit inconsistent with the one on line 46. Both this case (e.g., mv file.txt non-existent-dir/new-file.txt) and the case on line 46 (e.g., mv file.txt non-existent-dir/) are about the destination directory not existing. It would be clearer to use a consistent error message like 'Error: Destination directory does not exist' in both places.
