Review Summary

I am approving your solution because all core functional requirements of the pagination task are implemented correctly and there are no critical blockers. The Pagination component is stateless, uses the proper props, renders pages via getNumbers, correctly highlights the active page, and handles previous/next navigation with proper disabling and aria-disabled attributes. In App.tsx, you correctly track currentPage and perPage, slice the items for the visible range, and display the info text in the required Page X (items a - b of 42) format; the per-page selector has the correct options and resets to page 1 on change.

The only missing part is the optional React Router integration for syncing page and perPage with the URL (items [CHECKLIST ITEM #13] and [CHECKLIST ITEM #18]); since it is marked as optional, its absence does not block approval, but you should implement it if your specific variant requires it. For that, you would typically wrap the app in a Router and use something like useSearchParams to read initial page/perPage from ?page=2&perPage=7 and update the URL whenever these values change. As a minor improvement, consider renaming visisbleItems to visibleItems in App.tsx and optionally adding aria-current="page" to the active page link to further improve accessibility. Overall, the core behavior is solid and aligns well with the specification—nice work.

The task’s optional-but-marked requirement (#13/#18) about using React Router to sync page and perPage with the URL (?page=2&perPage=7) is not implemented here. If your current stage expects this, you’ll need to wrap the app with Router and use hooks like useSearchParams (or similar) to read initial values and update them when currentPage/perPage change.
