Review Summary
Great job on the overall implementation! However, a couple of changes are needed in the Pagination component to fully meet the core requirements.
First, the onPageChange callback is triggered even when clicking the active page. It should only be called when the page number actually changes. You can fix this by adding a condition to your onClick handler to check if the new page is different from the current one.
Additionally, the currentPage prop is defined as required, but the task specifies it should be optional with a default value of 1. Please update the PaginationProps interface to make it optional (e.g., currentPage?: number) and provide the default value within the component's props destructuring.
Once these two issues are addressed, your solution will be perfect. Keep up the great work!

Using the array index as a key can lead to issues if the list is ever sorted, filtered, or has items added/removed. It's better to use a unique and stable identifier from the data itself. In this case, since item is a unique string like "Item 1", you could use key={item} for better performance and predictability.

According to the task description, currentPage should be an optional prop with a default value of 1. You can update the interface to currentPage?: number; and then provide the default value in the component's destructuring: ({ currentPage = 1, ... }).

The requirements state that onPageChange should only be triggered if the page has changed. Currently, this function is called even if the user clicks on the active page. You should add a condition to check if page !== currentPage before calling onPageChange.
Also, since this <a> tag has an href attribute, you should accept the event object in your onClick handler and call event.preventDefault() to stop the browser from navigating.

Review Summary
Excellent work on fixing the onPageChange callback—that's a great improvement! We are very close to finishing this task. The only remaining issue is that the currentPage prop in Pagination.tsx is missing its required default value. While the type is correctly set to optional, the component itself must default it to 1.
Without this, if a parent component doesn't pass the prop, currentPage will be undefined, causing runtime errors in comparisons like currentPage > 1. You can fix this by setting the default directly in the props destructuring:
const Pagination = ({ currentPage = 1, total, perPage, onPageChange }) => {
// ... component logic
};Once that's added, everything will be perfect. Keep up the fantastic work!

While the currentPage prop is correctly typed as optional, it needs a default value here in the component. According to the requirements and the previous review feedback, it should default to 1. Without a default, if a parent component doesn't pass this prop, currentPage will be undefined and cause runtime errors in comparisons like currentPage > 1.
