How to Render Data in the UI in React

To render anything on the screen, we use the ReactDOM.render method in React.

It has the following syntax:

ReactDOM.render(element, container[, callback])
  • element can be any HTML element, JSX or a component that returns JSX
  • container is the element on the UI inside which we want to render the data
  • callback is the optional function we can pass which gets called once something is rendered or re-rendered on the screen

Take a look at the below code:

import React from "react";
import ReactDOM from "react-dom";

const rootElement = document.getElementById("root");

ReactDOM.render(<h1>Welcome to React!</h1>, rootElement);
