Review Summary

I am approving your solution because it meets all the functional requirements of the task and correctly implements the formatDate behavior. Your function properly uses the separators from fromFormat and toFormat, reorders the date parts according to the target format, and handles the YYYY ↔ YY conversions with the specified 20YY/19YY rule. Based on the described behavior, it should produce the expected outputs for the given examples and similar inputs, and there are no issues that would block task completion or break functionality.

One area you could improve for readability is variable naming—using camelCase (e.g., dateFinal instead of DATE_FINAL) is more conventional for non-constant values and makes the intent clearer. You might also consider slightly simplifying the year-conversion logic to avoid repeated conditions, which would make the code easier to follow while preserving the same behavior. Overall, you’ve implemented the core logic cleanly and in line with the constraints, so your work on this task is successful. Good job applying the requirements precisely.
