Great job on implementing the formatDate function! 🎉 While there are a few areas for improvement, such as making the year conversion logic more flexible and dynamically determining the separator, your code meets the core requirements and functions as expected. Keep up the good work, and consider these suggestions for future enhancements! 😊

The assumption that the separator is always at the fourth position in the format arrays (fromFormat[3] and toFormat[3]) may not be valid. Consider dynamically determining the separator by checking the format strings.

The logic here assumes that the year is always four characters long in the fromFormat and two characters long in the toFormat. This may not always be the case. Consider adding checks to ensure that the indices used are valid and handle cases where the year length differs.

The logic for converting two-digit years to four-digit years assumes that any year less than 30 should be prefixed with '20' and others with '19'. This may not be a valid assumption for all use cases. Consider making this logic more flexible or configurable.
