Review Summary

Your solution is approved because it meets the core functional requirements: it reads two CLI arguments, copies a file from source to destination, and correctly skips the copy when the resolved source and destination paths are the same, while using console.error() for error reporting. The main issue identified is not a critical blocker: inside src/app.js, you resolve absolute paths (e.g., absoluteSource, absoluteDestination) but still call fs.copyFileSync(sourceFile, destinationFile), which can lead to subtle inconsistencies if relative paths differ but resolve to the same location. To improve this, you should either use the resolved paths consistently in both the equality check and the copyFileSync call, or remove the resolution step and work only with the raw arguments. This is a clarity and robustness improvement rather than a required behavior change, so it doesn’t block approval. Overall, your implementation aligns with the task description, and with a small refactor around path handling, it will be even cleaner and more maintainable. Nice work getting the main behavior and error handling in place.

You resolve absolute paths but then ignore them in the actual copy call. This can lead to inconsistent behavior and makes the resolution code redundant; consider using absoluteSource and absoluteDestination in copyFileSync or removing the resolution logic altogether.
