Below is a simple React application that demonstrates some of React 18's features. This guide assumes you have a basic understanding of JavaScript and are using Node.js (14 or later) and npm. First, create a new React app using Create React App:

const LazyLoadedComponent = lazy(() => import('./LazyLoadedComponent')); code mosh react 18 beginners fco better

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: Below is a simple React application that demonstrates

import React, { useState } from 'react'; export default App

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

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 };
