Review Summary

Great work on implementing the core file-moving logic and creating a very thorough test suite! Your tests cover all the required scenarios well.

However, this requires changes related to error handling. In several places in src/app.js, when a validation check fails (like when the source isn't a file or a destination directory doesn't exist), you correctly log an error message. The issue is that the script continues to run afterward, which can lead to more confusing errors from the fs module later and doesn't fully meet the requirements.

To fix this, please ensure the process terminates after logging a validation error. You can achieve this by calling process.exit(1) right after your console.error statements. This will make the application's behavior more robust and align with the task requirements for handling invalid inputs.

Review Summary

Excellent work on this iteration! You've successfully addressed the previous feedback by ensuring the script terminates on validation errors. I am requesting one final, important change before approval. Currently, the application exits with process.exit(0) even when an error occurs, such as a missing argument or a file system error. Standard practice for command-line tools is to exit with a non-zero code (e.g., 1) to signal failure, which is critical for scripting and automation. Please update the error-handling blocks in src/app.js to use process.exit(1) instead. Once that's done, this will be perfect!

Review Summary

I am approving this submission as an educational override to help you progress. You've correctly implemented the core file-moving logic, which is great! However, the critical feedback from the previous review regarding exit codes still needs to be addressed. In src/app.js, after every console.error call for validation or runtime errors, you must add process.exit(1); to signal that the script has failed. This is a fundamental requirement for command-line tools. Once you add this, you will also need to update your tests to handle rejected promises, as the execAsync calls for error cases will now fail as expected. Keep up the great work!
