The Virtual DOM is a programming concept, popularized by libraries like React, in which an in-memory representation of the actual browser DOM is kept and updated first, then efficiently diffed against the previous version to minimize costly direct DOM manipulations. Front-end developers use it to improve web application performance and simplify UI updates, since manually manipulating the real DOM is comparatively slow. It underlies the reactive rendering model of frameworks like React and Vue.js.
