Review Summary

I am approving your solution because it fully meets the functional and formatting requirements for formatDate. Your function correctly accepts date, fromFormat, and toFormat, infers the separators from the format arrays, and reorders the date parts based on the target format. The year conversion logic is implemented as specified: converting YYYY→YY with slice(-2) and YY→YYYY using 20YY for years under 30 and 19YY otherwise, matching the required rules. I also verified that the examples described in the task produce the expected outputs with your implementation, including changes of separators and mixing YY/YYYY cases. You correctly assumed valid inputs without adding extra validation, which was explicitly required. Overall, the solution is concise, clear, and functionally complete—well done.
