Because the filtered data may have fewer pages. If the user is on page 5 and the filter only has 2 pages, they see nothing. Reset currentPage to 1 when filters change to ensure the user sees valid data.
Clamp the page number: currentPage = Math.max(1, Math.min(requestedPage, totalPages)). This ensures the page is always between 1 and the total number of pages.
Disable prev when currentPage === 1 and next when currentPage === totalPages. Use the disabled attribute: <button disabled={currentPage === 1}>Prev</button>. Style disabled buttons with reduced opacity.
