In a React application, the "root" div is typically chosen by using the ReactDOM.render() method, which renders the root component of the application into a specified DOM element. The root div is usually defined in the public/index.html file as a div element with an id of "root", and is selected using the document.getElementById() method in the ReactDOM.render() function. This is how the root element is selected:
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
ReactDOM.render(
<App />,
document.getElementById('root')
);
This code selects the root div with the id of "root" and renders the App component into it.
