Incorporating pagination into a React.js application enables you to present extensive datasets in more digestible segments. The implementation of pagination involves segmenting your data into pages, enabling users to navigate between them. Below is a step-by-step tutorial on how to integrate pagination into a React.js application [3][5]:
1. Set Up Your React App: Ensure you have a `React.js` application up and running. If you don't, you can create one using tools like create-react-app.
2. Install Necessary Dependencies: You may need to install some additional libraries to handle pagination. Popular choices include `react-paginate, react-bootstrap`, or `material-ui` for styling. Install your preferred library using npm or yarn:

    # Example using react-paginate
    npm install react-paginate

3. Create a Component for Displaying Data: Create a component that displays your data. For this example, let's assume you have an array of items to paginate:

    import React from 'react';

    const DataList = ({ data }) => {
      return (
        <ul>
          {data.map((item, index) => (
            <li key={index}>{item}</li>
          ))}
        </ul>
      );
    };

    export default DataList;

4. Create a Pagination Component: Create a pagination component using the library you installed in Step 2. Here's an example using react-paginate:

    import React from 'react';
    import ReactPaginate from 'react-paginate';

    const Pagination = ({ pageCount, onPageChange }) => {
      return (
        <ReactPaginate
          previousLabel={'Previous'}
          nextLabel={'Next'}
          breakLabel={'...'}
          pageCount={pageCount}
          onPageChange={onPageChange}
          containerClassName={'pagination'}
          activeClassName={'active'}
        />
      );
    };

    export default Pagination;

5. Manage Pagination State: In your main component or container component, manage the pagination state. Keep track of the current page and the number of items to display per page:

    import React, { useState } from 'react';
    import DataList from './DataList';
    import Pagination from './Pagination';

    const App = () => {
      const [currentPage, setCurrentPage] = useState(0);
      const itemsPerPage = 5; // Adjust this based on your preference
      const data = [...]; // Your array of data

      // Calculate the number of pages
      const pageCount = Math.ceil(data.length / itemsPerPage);

      // Handle page change
      const handlePageChange = ({ selected }) => {
        setCurrentPage(selected);
      };

      // Calculate the range of items to display
      const startIndex = currentPage * itemsPerPage;
      const endIndex = startIndex + itemsPerPage;
      const displayedData = data.slice(startIndex, endIndex);

      return (
        <div>
          <h1>Data Pagination Example</h1>
          <DataList data={displayedData} />
          <Pagination pageCount={pageCount} onPageChange={handlePageChange} />
        </div>
      );
    };

    export default App;

6. Style Your Pagination: Apply CSS or styling to your pagination component to make it visually appealing. Customize the pagination component according to your project's design.
7. Test Your Pagination: Start your React development server and test your pagination component. You should be able to navigate through different pages of your data.

Through the above steps, you have added pagination to your React.js application. Depending on the library you choose and your project's requirements, you may need to adjust the code and styling.
