Here's a simple example of a basic React.js component, which displays a counter with increment and decrement functionality:```javascriptimport React, { useState } from 'react';function Counter() { // Declare a state variable named 'count', initialized to 0 const [count, setCount] = useState(0); // Function to increment the count const increment = () => { setCount(count + 1); }; // Function to decrement the count const decrement = () => { setCount(count - 1); }; return ( <div style={{ textAlign: 'center', marginTop: '50px' }}> <h1>Simple Counter</h1> <p>Current Count: {count}</p> <button onClick={increment}>Increment</button> <button onClick={decrement}>Decrement</button> </div> );}export default Counter;```### How to Use This Code1. **Create a React Project**: If you haven't set up a React project yet, run: ```bash npx create-react-app my-app cd my-app ```2. **Add the Component**: - Create a new file named `Counter.js` in the `src` directory and paste the above code into it. - In `src/App.js`, import and render the `Counter` component like this: ```javascript import React from 'react'; import Counter from './Counter'; function App() { return ( <div> <Counter /> </div> ); } export default App; ```3. **Start the Application**: Run the following command to start the development server: ```bash npm start ```You will see a simple counter on the page with two buttons to increment and decrement the count!
