React Native is built using React. React, at its core, is a library for “diffing” a virtual DOM and executing this DOM to a screen with minimal operations. React, by default, does not have an idea about which nodes are in its virtual DOM tree. Instead, it simply has algorithms that can manage changes in the tree and re-render. React on the web provides its own node primitives (<div>, <span>, etc), which are the building blocks for web applications.

React Native defines its own primitives (<View>, <Image>, etc) which do not render HTML elements but instead map to native views, like UIView and UIImageView. It executes a bridge that allows the JavaScript runtime to communicate asynchronously with the native runtime. React itself gives the tree diffing and rendering infrastructure that allows React Native to work.
