Review Summary
Great work on implementing the core logic for the file copy utility! The argument parsing and validation checks are well-handled. However, this requires a change to the error handling. Currently, when an error is caught, the application exits with process.exit(0), which incorrectly signals success. For command-line tools, it's a standard convention to exit with a non-zero status code, such as process.exit(1), to indicate failure. This is crucial for automated scripts that rely on exit codes to determine if a command succeeded. Please update your catch block to exit with a non-zero code on error.

When an error occurs, it's a standard convention for command-line applications to exit with a non-zero status code to signal failure. An exit code of 0 indicates success. Consider changing this to process.exit(1) to correctly reflect that the program terminated due to an error.

Review Summary
I am requesting a change because a critical requirement for command-line applications has not been met. You've done a great job implementing the file copying logic and handling edge cases. However, the application still exits with a success code (0) even when an error occurs. For command-line tools, it's essential to signal failure with a non-zero exit code so that other programs or scripts can react to the error. Please add process.exit(1); to your catch block in src/app.js right after the console.error() call. Once that's fixed, your solution will be complete!

While you're correctly logging the error message, the program still exits with a success code (0). To align with command-line tool conventions and address the previous feedback, you should explicitly exit with a non-zero status code to indicate failure. Please add process.exit(1); after the console.error call.

But with process.exit(1) test failed

Review Summary
Excellent work on this file copying utility! Your solution is now complete and robust. I'm happy to confirm that your application now correctly handles all requirements, including edge cases like identical source and destination paths. It's great to see that you've successfully addressed the feedback from the last review by ensuring the process exits with a non-zero status code on error. This is a crucial detail for command-line tools. Your code is clean and well-structured. I am approving this submission, well done!
