Other APIs

Beyond components, props, and Hooks, React and ReactDOM expose a handful of lower-level APIs you'll encounter less often. This section covers React.createElement(), React.cloneElement(), and the React.Children utilities (what JSX actually compiles down to), ReactDOM.findDOMNode() (a legacy escape hatch for reaching a DOM node), and component.forceUpdate() (a rarely-needed, class-component-only way to force a re-render).
