Thank you for your hard work on the formatDate function! While your solution meets many of the task requirements, there are a few critical issues that need to be addressed before we can approve the pull request. Specifically, the logic for determining the separator in both fromFormat and toFormat is incorrect, as it assumes the separator is the last element of the array. Additionally, the handling of two-digit years needs adjustment to ensure the correct order of operations. Please address these issues to ensure the function works as intended. Keep up the great work, and I'm confident you'll have this resolved in no time! 😊

The logic for determining the separator is incorrect. The separator is not necessarily the last element of the fromFormat array. You should consider a different approach to identify the separator used in the date string.

The logic for handling two-digit years is incorrect. The expression +splitDate[i] < 30 will not work as intended because the unary plus operator has higher precedence than the addition operator. Consider using parentheses to ensure the correct order of operations.

Similar to the issue with fromFormat, the logic for determining the separator in toFormat is incorrect. The separator is not necessarily the last element of the toFormat array.

Great job on implementing the formatDate function! 🎉 Your solution meets the task requirements and constraints, effectively identifying the separator from the fromFormat array and handling the conversion between two-digit and four-digit years. However, there are some critical issues that need attention:
- Separator Logic: The current logic assumes the first non-date part is the separator, which might not be accurate if multiple separators exist. Consider using a regular expression to extract the separator from the date string to improve accuracy.
- Final Return Statement: The
slice(0, -1)call ontoFormatis incorrect as it removes the last element of the array, potentially omitting a necessary part of the format. Ensure all parts oftoFormatare included in the final result.
These improvements will enhance the functionality of your code. Remember, addressing these issues is crucial for future tasks to avoid similar problems. Keep up the great work and continue learning from these experiences! 🚀

The logic for determining the new separator is incorrect for the same reason as the fromFormat separator. Ensure that you correctly identify the separator used in the toFormat.

The slice(0, -1) call on toFormat is incorrect as it removes the last element of the array, which might be a necessary part of the format. Ensure that all parts of toFormat are included in the final result.
