Your implementation of the formatDate function is well done and meets the task requirements effectively! 🎉 While there are a few areas for potential improvement, such as ensuring that all format parts are correctly mapped and handling separators more dynamically, these do not detract from the core functionality of your solution. Keep up the great work, and consider these suggestions for future enhancements to make your code even more robust! 😊

The use of fromFormat[3] to split the date string assumes that the separator is always at index 3. This might not be the case if the format changes. Consider dynamically determining the separator or passing it as a separate parameter.

Similarly, toFormat[3] is used as the separator for joining the new date format. Ensure that this index is correct for all possible formats or handle separators separately.

The loop iterates over fromFormat.length - 1, which might miss the last element if the format array is longer than expected. Consider iterating over the entire array to ensure all parts are mapped.

The logic for handling 'YY' and 'YYYY' conversions is correct, but ensure that dateMap contains the necessary keys before accessing them to avoid potential undefined errors.
