Otherwise just tick on the box before “I accept the terms in the license agreement” and then click on the Next button. 

Next, you will see the destination folder popup where you can change the destination folder of node.js according to your requirement. I will recommend you to leave it as it is. And then click on the Next button again as shown in the picture.

Now you are on the custom setup page of the node.js installation process. Here you can see that Node Package Manager (NPM) is also listed below the node.js run-time in this page. And it will automatically install with node.js by clicking the Next button again.

Step 4:- Run Your First Node.js Program:

Now it is the time to run your first node.js program to check how node.js run-time works on your command prompt as well as on your system browser.

Create a simple test file and run it on command prompt:

For this test you have to open your notepad and type this code 

console.log('I like your article Mr. Shubham Vishwakarma!');

And save it as a JavaScript file with a name hello.js on your desktop.

To run this code you have to just open your command line program and navigate to the desktop by typing this code cd desktop on your command line as shown in figure then hit the enter button.

Next, you have to type the final code that is node hello.js and hit the enter button.

Now it starts the node.js run-time and run the code of hello.js file.

You can see the output "I like your article Mr. Shubham Vishwakarma!"

Bingo, you have successfully tested your first node.js program on your command prompt. But if you want to see the same output on your browser, then you have to make some changes discussed below-

Create a test file and run it on your Browser:

Open your notepad and paste this code given below.

const http = require('http');
const hostname = '127.0.0.1';
const port = 3000;
const server = http.createServer((req, res) => {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain');
res.end('I like this article Mr. Shubham Vishwakarma\n');
});
server.listen(port, hostname, () => {
console.log(`Server running at http://${hostname}:${port}/`);
});

And save it as a JavaScript file with name hello.js on your desktop. You can copy the same code from this link https://nodejs.org/en/about/.

To run this code, open your command line program and navigate to the desktop by typing this code cd desktop and hit the enter button.

Next, type the final code node hello.js and hit the enter button.

Now you will see some kind of different output from the above test output. This output shows a link http://127.0.0.1:3000/

Copy this link and paste it into your browser and hit enter. Now you are ready to see the same output in your browser that is “I like this article Mr. Shubham Vishwakarma”.
