        "React.js, developed by Facebook, stands as a pivotal JavaScript library revolutionizing front-end web development. At its core lies a component-based architecture, empowering developers to construct reusable, encapsulated UI components, leading to cleaner and more maintainable codebases. Central to React's efficiency is its virtual DOM implementation, enabling lightning-fast rendering by selectively updating only the portions of the DOM that have changed. This approach enhances performance and user experience, particularly in complex applications. With JSX, a syntax extension blending HTML-like code within JavaScript, React facilitates the creation of declarative and expressive UIs. " +

    res.json({ keywords: response.data.choices[0].text.trim() });
  } catch (error) {
    console.error("Error:", error);
    res.status(500).json({ error: "An error occurred" });

app.listen(port, () => {
  console.log(`Server is running on http://localhost:${port}`);
});
