Rendering JSX Elements in React

API
In React 18 and later, react-dom
handles rendering these components into the DOM and updating them efficiently using an API called createRoot
. It connects the React application to the browser's DOM and is responsible for displaying our UI. This new API offers better performance and enables concurrent rendering, making React applications more efficient and responsive.

How createRoot
works

method is used to create a React root container for rendering. Once the root container ...
