Certainly! Below is a simple "Hello, World!" program in a file named `index.js`. This is a basic Node.js script that logs "Hello, World!" to the console. ```javascript // index.js console.log("Hello, World!"); ``` To run this script, make sure you have Node.js installed on your system. Save the above code in a file named `index.js`, then open your terminal or command prompt, navigate to the directory where `index.js` is saved, and run the following command: ```bash node index.js ``` You should see the output: ``` Hello, World! ``` If you want to embed this in an HTML file and render it in a browser using an iframe, you can create an HTML file like this: ```html Hello World

Hello, World!

``` However, since `index.js` is a Node.js script, it won't run directly in a browser. If you want to achieve a similar effect in the browser, you can modify `index.js` to be a client-side JavaScript file that interacts with the DOM: ```javascript // index.js (for browser use) document.addEventListener('DOMContentLoaded', function() { document.body.innerHTML += '

Hello, World!

'; }); ``` Then, ensure your `index.html` includes this script. Here’s the complete setup: ```html Hello World ``` And here’s the full code block including the HTML and JavaScript for browser rendering: ```html Hello World ``` This HTML file can be opened directly in a browser, and it will display "Hello, World!" without needing an external `index.js` file.
