node js in windows cannot run a Hello World program in js

I am quite new to Node.js and i am facing problem in running a simple 'hello world' program in Node.js

program1:

console.log("hello world");

program2:

var http = require('http');

http.createServer(function (request, response) {
    response.writeHead(200, {'Content-Type': 'text/plain'});
    response.end('Hello World\n');
}).listen(8124);

console.log('Server running at http://127.0.0.1:8124/');

After running both the programs,this is how the terminal continues looks:

>node hello.js
