Virtual DOM
At the end of the day, React elements are nothing more than a never-changing (immutable) JavaScript object containing properties to tell React how and what exactly needs to be displayed. React uses this description of properties to construct a virtual blueprint of the component hierarchy. It resembles the way HTML trees are represented as a JavaScript object.
