Review Summary

Your solution is approved because it meets all the functional requirements of the task and behaves correctly for the specified date conversions. The formatDate function correctly uses fromFormat and toFormat to determine separators, split the input date, reorder parts, and join them into the new format. You also handled year conversions properly: YYYY to YY via the last two digits and YY to YYYY using the 20YY/19YY rule with the appropriate threshold. The absence of input validation is acceptable here, since the task explicitly states that validation is not required and inputs can be assumed correct.

As a minor improvement (not required for this task), you could make the code a bit more readable by using consistent property access, for example preferring fromDate.DD over fromDate['DD'] when possible. Overall, your implementation is clear, focused on the requirements, and functionally complete—well done.
