Write a program that performs an HTTP GET request to a URL provided to you as the first command-line argument. Write the String contents of each "data" event from the response to a new line on the console (stdout).
For this exercise you will need to use the http core module.
Documentation on the http module can be found by pointing your browser here:
/node_apidoc/http.html
The http.get() method is a shortcut for simple GET requests, use it to simplify your solution. The first argument to http.get() can be the URL you want to GET; provide a callback as the second argument.
Unlike other callback functions, this one has the signature:
function callback (response) { /* ... */ }
Where the response object is a Node Stream object. You can treat Node Streams as objects that emit events. The three events that are of most interest are: "data", "error" and "end". You listen to an event like so:
response.on("data", function (data) { /* ... */ })
The "data" event is emitted when a chunk of data is available and can be processed. The size of the chunk depends upon the underlying data source.
The response object / Stream that you get from http.get() also has a setEncoding() method. If you call this method with "utf8", the "data" events will emit Strings rather than the standard Node Buffer objects which you have to explicitly convert to Strings.
