What are the functions of react-dom?

The main functions of react-dom are as follows: 1. Rendering React components: react-dom provides a render method to render React components to the DOM. By calling the render method, you can render a React component into actual DOM elements and insert it into a specified container. 2. Updating the DOM: The render method in react-dom can be used not only for initial rendering but also for updating existing DOM. When the state or props of a React component change, you can call the render method to render the new component into a new DOM and update it on the page. 3. Event handling: react-dom provides an event system for handling DOM events. Through react-dom’s event system, you can bind DOM events to React components to handle events and update state. 4. Managing the virtual DOM: react-dom internally manages and operates on the virtual DOM. The virtual DOM is one of React’s core concepts, and it allows for efficient page updates. react-dom provides methods for creating, updating, and manipulating the virtual DOM. In summary, the main purpose of react-dom is to render React components to the DOM and provide methods for updating the DOM, handling events, and managing the virtual DOM.
