Which of the following statements accurately describes React's Virtual DOM?
Which of the following statements accurately describes React's Virtual DOM?
- It is a technique to manipulate the real DOM directly, optimizing performance.
- It is a server-side rendering technique used to enhance initial loading speed.
- It is an exact copy of the real DOM, constantly updated.
- It is a lightweight representation of the real DOM, created and updated to efficiently calculate changes. (correct)
What is the primary benefit of using React components?
What is the primary benefit of using React components?
- Components separate UI logic from data logic, promoting better code organization.
- Components enable complex data manipulation and backend integration within the user interface.
- Components allow for easy duplication of UI elements, reducing code redundancy.
- Components can be easily shared and reused across different parts of an application, making development faster. (correct)
How does ReactJS handle updating the user interface based on changes in the application's data?
How does ReactJS handle updating the user interface based on changes in the application's data?
- React directly modifies the real DOM, updating elements based on changes.
- React utilizes a Virtual DOM to determine the minimal changes required for efficient updates. (correct)
- React utilizes a procedural approach, where the update process is explicitly defined in a step-by-step manner.
- React avoids any direct DOM manipulation, relying solely on server-side rendering.
