The Virtual DOM is an in-memory representation of the real DOM elements generated by a UI library such as React. It allows for efficient updates and rendering by minimizing the number of changes made to the actual DOM.
How does the Virtual DOM improve performance?
The Virtual DOM improves performance by batching updates and only applying the necessary changes to the real DOM, reducing the number of direct manipulations and enhancing rendering efficiency.
What is the difference between the Virtual DOM and the real DOM?
The Virtual DOM is an in-memory representation that allows for efficient updates, while the real DOM is the actual structure rendered in the browser. The Virtual DOM helps optimize interactions with the real DOM.
Which libraries use the Virtual DOM?
Libraries that use the Virtual DOM include React, Preact, and Vue.js, leveraging its benefits for efficient rendering and updates.
