Review Summary
Excellent work on this task! Your script successfully meets all the requirements by dynamically adding labels and placeholders to the form inputs. The logic is solid and everything functions as expected, so I am approving your solution.
As a small suggestion for future improvement, consider using .forEach() instead of .map() when you are iterating over elements to perform actions, like modifying the DOM. While .map() works here, .forEach() is semantically more accurate for this use case because you aren't using the new array that .map() returns. This is a minor point about idiomatic code, and your current implementation is great. Keep up the fantastic work!

While using .map() works here, it's generally intended for creating a new array from an existing one. Since you are performing actions with side effects (modifying the DOM) and not using the new array that .map() returns, using .forEach() would be more semantically correct for this situation.
