Difference between React and ReactDOM

React and ReactDOM are two distinct libraries that are commonly used together in the development of web applications with React.

React is a JavaScript library focused on building user interfaces. It follows a declarative approach, where developers define what the UI should look like based on the current state of the application. React then efficiently updates and renders components as the state changes. Its design emphasizes flexibility and efficiency, making it a popular choice for developing both web and mobile applications.

ReactDOM, on the other hand, serves as a bridge between React and the DOM (Document Object Model). The DOM is a hierarchical structure representing the HTML content of a web page. ReactDOM provides a set of methods that enable React components to be rendered and updated within the DOM. It ensures that the user interface is synchronized with the underlying HTML structure.

In summary, React is a library for building user interfaces, while ReactDOM handles the interaction with the DOM, rendering React components onto the web page. Although they are often used together, they serve different purposes and can function independently of each other.
