NodeJs Getting Started (Creating an empty Server)

Server.js

// #First HomeWork :)

const 
    http = require('http'),
    host= '127.0.0.1',
    port = 2999, // For showing my Creativity!
    server = http.createServer( (req , res)=>{
    res.statusCode = 200;
    res.setHeader('Content-Type','text/html');
    res.write('<p>Dalam :)</p>');
    res.write('<p>Will it go to the next line?</p>');
    res.write('<p>It <b>didn\'t</b> unless I used html</p>');
    res.end();
    }),
    createMyServer = ()=>{
            server.listen(3000,'127.0.0.1', ()=>{
            console.log('Can anyone say why PORT is the first argument? :|');
        });
    };

createMyServer();
