The answer
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.

How do you handle prev/next buttons at boundaries in pagination?
More FAQs in Pagination Common Mistakes and Fixes
Not clamping the page number, no ellipsis for many pages, not resetting page on filter change, no disabled state for prev/next at boundaries, not updating total pages on data change, and no loading state for server-side pagination.
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.
