Write a function. Test real cases. Improve your solution.
Return {items, page, totalPages, hasNext} for a requested page of a results array. requestedPage and pageSize are positive integers. totalPages is the number of pages needed for all results. Clamp the requested page to the last available page; use page 1 with totalPages 0 when results are empty. items contains that page of results, and hasNext is true only when another page exists after the returned page. Leave the input unchanged.
