Review Summary
Great job implementing the core logic for moving and renaming files! The main functionality works well. However, I'm requesting a change because the error handling doesn't fully meet the requirements. When a destination directory does not exist, the task requires that an error be thrown, but your code currently logs a message to the console and returns. Please update this to throw new Error(...) to ensure the application behaves as expected.
As a smaller improvement, there is an unreachable if block in src/app.js. Removing this will make your code cleaner and easier to maintain. Keep up the great work!

This if block is unreachable. The logic for when isDestinationDirectory is true is already completely handled by the if block on lines 33-51, which always concludes with a return statement. This redundant check should be removed.

The task requirements state that an error must be thrown if the destination directory does not exist. This implementation prints an error to the console and returns, which does not meet the requirement. This should be changed to throw new Error(...) to ensure consistent error handling.

Review Summary
Great job on removing the unreachable code from the previous review—the code is much cleaner! However, this requires changes because a critical error-handling requirement is still not met.
When a destination path ends with a / (e.g., non_existent_dir/) and that directory does not exist, the application must throw new Error(). Currently, your implementation renames the source file to non_existent_dir instead.
To fix this, you need to add a specific check. Before attempting the rename operation, if the destination string ends with a /, you should first verify that the directory exists. If it doesn't, then you should throw the required error. You're very close to finishing this!

This block of code doesn't meet a key requirement. If the destination ends with a /, the app should treat it as a directory and throw an error if that directory does not exist. Currently, your code will rename the source file instead of throwing an error in this scenario. You need to add a check for this specific case before attempting the rename operation.

Review Summary
Excellent work addressing the main issue from the previous review! I am approving this submission so you can continue to the next task, but I want to point out a couple of areas for improvement.
For future reference, please note:
- When the destination's parent directory doesn't exist, the application logs an error instead of throwing one, which doesn't meet the requirements. Remember to use
throw new Error()for all required error conditions. - There is an
ifblock that is unreachable because its condition is fully handled by earlier logic in the function. Removing such code will make your functions cleaner and easier to maintain.
You're doing a great job. Keep up the fantastic progress!

This if block is unreachable. The case where isDestinationDirectory is true is fully handled by the logic starting on line 33, which always exits the function with either a return or a throw.

According to the requirements, an error must be thrown if the destination directory does not exist. This check correctly identifies a non-existent parent directory but uses console.error instead of throwing an error. Please change this to throw new Error(...) to conform to the requirements.
