Review Summary
Excellent work on the file copying application! Your solution is approved because it meets all the functional requirements, including argument parsing, path validation, and handling the copy operation correctly. While your use of console.error is correct, the error messages are generic. For future projects, consider making them more descriptive to improve usability, for example: Error: Invalid number of arguments. Usage: node app.js <source> <destination>. This helps users understand what went wrong. Keep up the great work!

While this meets the requirement of using console.error, a more descriptive error message would be more helpful for the user. For instance, you could explain the correct usage, like Usage: node app.js <source> <destination>.
| if (!srcStat.isFile()) { | ||
| console.error('Error'); | ||
| } else if (fs.existsSync(dest) && fs.statSync(dest).isDirectory()) { | ||
| console.error('Error'); |

It's great that you've added these checks for the source and destination paths. To make the tool more user-friendly, consider providing more specific error messages here instead of a generic 'Error'. For example, you could inform the user if the source is not a file or if the destination is a directory.
