Our next goal in our ongoing journey with the previous app is to construct the "Products" page. This page will serve as a platform for rendering data provided from the `data.js` file, allowing us to interact with it.

We begin by creating the `ProductsPage` component. The component structure is as follows:

```js
import React, { useState } from "react";

const ProductsPage = ({ data }) => {
  const [companies, setCompanies] = useState(data);

  const handleChange = (e) => {
    // Handle user input and update the state (companies in this case)
  };

  return (
    <>
      <input type="text" onChange={handleChange} />
      <ul className="companyList">
        {companies.map(({ id, companyName, companyDescription }) => (
          <li key={id}>
            <h2>{companyName}</h2>
            <p>{companyDescription}</p>
          </li>
        ))}
      </ul>
    </>
  );
};

export default ProductsPage;
```

- We've established a React component named `ProductsPage`. This component is designed to handle the rendering of a list of companies;
- The `useState` hook initializes the `companies` state. This state will enable the component to manage and respond to changes in the list of companies;
- The `handleChange` function is set up to handle user input and trigger updates based on the input.

With this `ProductsPage` component in place, we can render a dynamic list of companies and allow user interaction with the data.

Delve into the world of routing within React applications and learn how React Router streamlines the management of navigation, URL state, and dynamic component rendering, all in response to the current URL.

Learn the theoretical basics of concepts such as URL, domain, protocol, query parameters, and more. Understand the significance of routing in web applications and why we need the React Router library.

Discover how to create an entire React application from scratch, with the ability to display content that adapts based on the URL using React Router functionality.

Explore using query strings for sharing and managing application state via URLs, work with different data types in query parameters, and leverage React Router for navigation and effects based on URL changes.
