Thank you for your hard work on the formatDate function! 😊 While your implementation covers many of the task requirements, there are a few critical issues that need to be addressed before we can approve the changes.
-
Year Conversion Logic: The current logic for converting between 'YY' and 'YYYY' formats has some flaws. Specifically, it does not handle cases where
shortYearis zero, and the assumption about years being in the 1900s or 2000s may not always hold true. Consider making this logic more robust or configurable. -
Redundant Operations: The
date.split(fromSpliter)[i]operation is repeated multiple times within the loop. Optimizing this by storing the split result in a variable before the loop can improve efficiency. -
Splitter Logic: The assumption that the last element of the format arrays is the splitter might not always be correct. Please ensure that the format arrays are structured correctly to avoid potential errors.
Once these issues are addressed, your code will be in great shape! Keep up the great work, and I look forward to seeing your improvements. 🚀

The logic for determining the splitters (fromSpliter and toSpliter) assumes that the last element of the format arrays is the splitter. This might not always be correct. Ensure that the format arrays are structured such that the last element is indeed the splitter.

The date.split(fromSpliter)[i] operation is repeated multiple times within the loop. Consider splitting the date once before the loop and storing the result in a variable to avoid redundant operations.

The logic for handling 'YY' and 'YYYY' conversions is incorrect. When converting 'YY' to 'YYYY', the code should handle cases where shortYear is zero, which currently isn't addressed. Similarly, when converting 'YYYY' to 'YY', ensure that the conversion logic correctly extracts the last two digits.

The conversion logic from 'YY' to 'YYYY' assumes that years less than 30 are in the 2000s and others are in the 1900s. This assumption may not always be valid. Consider making this logic configurable or more robust.

Great job on implementing the formatDate function! 🎉 While the function has been improved, there are a few areas that need attention to fully meet the task requirements:
-
Year Conversion Logic: The conversion from 'YY' to 'YYYY' needs to be more robust. Currently, it assumes years less than 30 are in the 2000s, which might not always be accurate. Consider refining this logic to handle edge cases, especially when the year is zero or near a century boundary.
-
Redundant Operations: Try to optimize the code by reducing redundant operations, such as accessing
fromArray[i]multiple times within the loop. Storing the result in a variable before the loop could improve efficiency. -
Splitter Logic: The assumption that the last element of the format arrays is the splitter might not always be correct. Revisit this logic to ensure the correct splitter is identified and aligns with the task requirements.
Your effort is commendable, and these improvements will help you enhance your coding skills. Keep up the good work, and make sure to address these issues in future iterations to avoid similar problems. Happy coding! 😊

The logic for converting a long year to a short year seems to be correct, but ensure that the conversion handles all edge cases, especially when the year is zero or close to the century boundary.

The logic for converting a short year to a long year is improved, but it still assumes that years less than 30 are in the 2000s and others are in the 1900s. This assumption might not hold for all cases, so consider making this logic more robust.

you can simplify it using the switch case
