export default Counter; Create another component, LazyLoadedComponent.tsx :

const handleClick = async () => { // Before React 18, setCount would not batch with async code // Now, React 18 automatically batches updates setCount(count + 1); await fetch('https://example.com/api/data'); // State updates here will batch with the previous setCount };

export default LazyLoadedComponent; Then, modify App.tsx to use React.lazy and Suspense :

import React, { lazy, Suspense } from 'react'; import './App.css'; import Counter from './Counter';

const LazyLoadedComponent = () => { return <div>This component was lazy loaded!</div>; };

import React, { lazy, Suspense } from 'react'; import Counter from './Counter';
