Review Summary

Your solution is approved because it fully meets the functional requirements for formatDate. The function correctly parses the input date using the separator defined by the last element of fromFormat, maps tokens like DD, MM, YY, and YYYY to their values, and then reconstructs the output using toFormat and its separator. You implemented the 2-digit to 4-digit year logic as specified: YY < 30 maps to 20YY, YY ≥ 30 maps to 19YY, and you also derive YY from YYYY using the last two digits, which satisfies the year-conversion rules. The function supports reordering of date components and changing separators (e.g., YYYY-MM-DD to DD/MM/YY) without adding extra validation, which aligns with the constraint that the inputs are assumed to be correctly formatted. Overall, the behavior matches the task’s checklist items, and there are no critical or blocking issues to address.

If you want to further improve this in your own time (not required for this task), you could consider adding optional validation or clearer variable names, but functionally your implementation is solid and complete.
