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

const Counter = () => { const [count, setCount] = useState(0);

Creating a full piece of code for a beginner's guide to React 18, as discussed in a Mosh Hamedani tutorial (assuming "Mosh" refers to Mosh Hamedani, a well-known instructor), involves setting up a basic React application and explaining key concepts. React 18 introduces several new features and improvements over its predecessor, such as automatic batching, new rendering strategies (like React.lazy), and better suspense support. code mosh react 18 beginners fco better

import React, { useState } from 'react';

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 Counter

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

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

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