Review Summary
Great work on implementing the core file copying functionality! You've correctly handled the case where the source and destination paths are the same. However, I am requesting a change to your command-line argument validation.
Currently, the application crashes with a TypeError if it's run with zero arguments. This happens because your validation logic only checks for one argument but allows the zero-argument case to fall through to the file copying logic, which then fails.
To fix this, please adjust the condition in src/app.js to ensure the program only proceeds when the number of arguments is exactly two. A more robust check like if (params.length !== 2) would handle all incorrect argument counts and prevent this crash.

This condition only handles the case where exactly one argument is provided. If zero arguments are given, the else block is executed, which will cause the application to crash. The validation should ensure that the number of arguments is exactly two to prevent this unhandled error.

Excellent work on this submission! I'm happy to approve it. You've successfully addressed the command-line argument validation issue from the previous review. The application is now robust, correctly handles an incorrect number of arguments, and meets all the specified requirements. Great job!
