Thank you for your hard work on the 'Bulls & Cows' game! 🎉 While your implementation is mostly correct, there are a few critical issues that need to be addressed to ensure the game functions as intended.
-
Random Number Generation: The logic for generating a 4-digit number with unique digits needs improvement. Currently, it may produce numbers with fewer than 4 digits or with leading zeros. Please adjust the logic to ensure the number is always 4 digits long, with the first digit non-zero and all digits unique.
-
User Input Handling: When the input is invalid, the program should not proceed to calculate bulls and cows. Instead, it should prompt the user to try again. Adding a
returnstatement after displaying the invalid input message will help in preventing further execution and allow the user to input again.
Once these issues are resolved, your code will be ready for approval. Keep up the great work, and I'm confident you'll nail these changes! 💪

Currently, if the input is invalid, the program only writes an error message but does not return or prompt the user to input again. You should add a return statement after writing the INVALID_INPUT_MESSAGE to prevent further execution of the code block and prompt the user to try again.

The current logic for generating random numbers only produces digits from 1 to 9. This ensures no leading zero, but the logic for ensuring exactly 4 unique digits is flawed. Consider modifying the logic to ensure the first digit is non-zero and the remaining digits are unique, potentially by generating the first digit separately and then filling the rest.

The conversion of the set to a number may result in fewer than 4 digits if the set contains leading zeros. Ensure that the number is always 4 digits long by adjusting the logic to handle leading zeros appropriately.

Review Summary
Great job on implementing the 'Bulls & Cows' game! 🎉 Your code is mostly correct, but there are a couple of critical issues that need attention to ensure the game functions as intended:
-
Random Number Generation: The
generateRandomNumberfunction is designed to create a 4-digit number with unique digits. However, due to the unordered nature of sets, the current logic might not always produce a valid 4-digit number. Consider using an array to maintain the order of digits and ensure the first digit is always non-zero. -
User Input Handling: In
app.js, the program currently continues execution even when the user input is invalid. To prevent this, add areturnstatement after displaying the invalid input message. This will ensure that the user is prompted to input again without proceeding to calculate bulls and cows.
These improvements are crucial for the functionality of the game. Addressing them will enhance the user experience and ensure the game operates correctly.

The current implementation may not guarantee a 4-digit number due to the unordered nature of sets. Consider using an array to maintain the order of digits and ensure the first digit is always non-zero.
