Review Summary
I am requesting a few changes to your solution. You've correctly implemented the core logic for moving files, which is a great start. However, there are two critical issues that need to be addressed to meet the requirements.
First, the application must only support moving files, but the current implementation doesn't check if the source path is a file. This could lead to attempts to move directories. You can fix this by using fs.stat() to check the source path and ensure it's a file with stats.isFile() before attempting the move.
Second, the error handling needs to be more precise. When a destination directory doesn't exist, the requirement is to throw a specific error, but your code logs a generic message. Similarly, the error messages for missing arguments could be clearer (e.g., 'Source file path was not provided').
Addressing these points will make your application more robust and fully align with the task requirements.

This error message is slightly misleading. At this point, the program is checking for the presence of a command-line argument, not for the existence of a file on the filesystem. A clearer message might be 'Source file path was not provided'.

Similar to the previous check, this error message could be more precise. It's checking for a missing command-line argument, not a path on the filesystem. Consider changing it to something like 'Destination path was not provided'.

The requirement states that the app must support moving only files. fs.access checks for existence, but it doesn't distinguish between files and directories. This means your current implementation would also attempt to move a directory. You should use fs.stat to ensure the originPath is indeed a file.

This catch block handles errors from both fs.access on the source path and fs.rename for the move operation. Both can throw an ENOENT error, but for different reasons (source not existing vs. destination directory not existing). By using one generic message 'File does not exist', you provide misleading information when the destination directory is missing. Consider separating the logic to handle these errors differently to provide more accurate feedback.

Review Summary
Great job addressing the previous feedback to check if the source is a file! That logic is now correct. However, this submission requires changes because the error handling does not meet the task requirements. When an error occurs, such as a non-existent destination directory, the application logs a message and exits successfully instead of throwing an error. This is a critical issue because it incorrectly signals that the operation succeeded. Please adjust the code to throw new Error(...) in failure scenarios, which will cause the process to exit with a non-zero status code, correctly indicating that a failure occurred.

The requirement states that an error must be thrown if a destination directory does not exist. Logging an error and returning causes the program to exit with a success code (0), which incorrectly signals that the operation succeeded. You should throw new Error(...) here instead.

How should I do this if Cypress tests don't support this option, and exiting via process.exit(1) doesn't work either?

This catch block prevents the application from signaling a failure when an error occurs during the fs.rename operation (for example, if an intermediate directory in the destination path doesn't exist). By catching the error and only logging it, the script finishes with a success exit code. For a command-line tool, it's better to let the error propagate (by removing this try...catch block or re-throwing the error) so that the process exits with a non-zero status code, indicating failure.

Review Summary
I am approving your solution as an educational override so you can continue to make progress. You've done an excellent job with the core logic for moving files and correctly distinguishing between file and directory destinations!
The main area for improvement is error handling. Your current implementation uses console.error() and then returns, which causes the program to exit with a success code (0), even when something goes wrong. The requirement is to signal a failure by terminating with a non-zero exit code.
To achieve this, please replace all error-handling blocks like console.error(...); return; with throw new Error(...). This is a crucial practice for writing reliable scripts. Great effort, and I look forward to seeing your next submission!

According to the requirements, when a destination directory does not exist, an error must be thrown. Using console.error and returning from the function will cause the process to exit successfully (with code 0), which incorrectly indicates that the operation succeeded. Please throw new Error(...) here instead.

This catch block handles errors from fs.rename but suppresses them by only logging the message. Any error during the file move, such as a non-existent parent directory in the destination path, should cause the application to fail. An error should be thrown here to ensure the process exits with a non-zero status code, signaling a failure.
