Express App: Hello World!

Create an Express.js app that outputs "Hello World!" when somebody goes to /home.

The port number will be provided to you by expressworks as the first argument of the application, ie. process.argv[2].

HINTS

This is how we can create an Express.js app on port 3000, that responds with a string on '/':

var express = require('express')
var app = express()
app.get('/', function(req, res) {
  res.end('Hello World!')
})
app.listen(3000)

Please use process.argv[2] instead of a fixed port number:

app.listen(process.argv[2])

My Solution

var express = require('express')
var app = express()
app.get('/home', function(req, res) {
  res.end('Hello World!')
})
app.listen(process.argv[2])

It is similar to node which in turn is similar to JavaScript so everything is easier to pickup.
