import React, { useState } from 'react';

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

export default App; To see automatic batching in action, you can modify Counter.tsx to include a function that updates state and then uses fetch to make an API call: code mosh react 18 beginners fco better

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

const Counter = () => { const [count, setCount] = useState(0); import React, { useState } from 'react'; import

export default Counter; Here's how App.tsx could look:

function App() { return ( <div className="App"> <header className="App-header"> <Counter /> <Suspense fallback={<div>Loading...</div>}> <LazyLoadedComponent /> </Suspense> </header> </div> ); } { useState } from 'react'

const LazyLoadedComponent = lazy(() => import('./LazyLoadedComponent'));

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