how to create a server in Nodejs

First, you need to install Nodejs from official website

then you need to create a new file  myServer.js

after that, you need to add this snippet code to the previous file 

var http = require('http');

 http.createServer(function(req,res){
	res.writeHead(200,{'Content-Type': 'text/html'});
	
	res.write("Server Run");

	res.end();
 }).listen(801);

now  you need to run this code in the command line 

$ node myServer.js

then you can access your browser at http://localhost:801/

you will see the result Server Run
