    As a JavaScript library running in the browser, it may lead to increased CPU and memory usage, especially for large or complex web pages.
  • Security Concerns
    Rendering content on the client side may expose sensitive information within the page during the rendering process, posing security risks if not handled carefully.

    Dynamic content like videos, animations, or elements with JavaScript-based changes during rendering might not be accurately captured.
