reactjsHow do I create an app using ReactJS?
-
To create an app using ReactJS, you need to install the React and ReactDOM libraries. You can do this with npm by running
npm install react react-dom
. -
Then, create a new file called
index.js
and add the following code:
import React from 'react';
import ReactDOM from 'react-dom';
ReactDOM.render(
<h1>Hello, world!</h1>,
document.getElementById('root')
);
-
This code will render the text "Hello, world!" in an element with the ID of
root
(which you'll need to add to your HTML file). -
Next, create an HTML file called
index.html
and add the following code:
<html>
<head>
<title>My React App</title>
</head>
<body>
<div id="root"></div>
<script src="index.js"></script>
</body>
</html>
-
Now, open
index.html
in your browser and you should see the text "Hello, world!" -
To build a more complex app, you can create components and render them in the
index.js
file. You can also use libraries like React Router to handle routing. -
