I can't really understand what exactly is required in this challenge?

Concatenate in the var request?

app.js 
var http = require("http");
var request = http.get("http://teamtreehouse.com/chalkers.json", function(response){
    var responseBody = "data"+ " "+ "error";

    response.on("data", function(dataChunk) {
      console.log(responseBody);
    });

    response.on("", function(){
        console.log(responseBody);
    });

});

request.on("error", function(error){
    console.error(error.message);
});

 var http = require("http");
var request = http.get("http://teamtreehouse.com/chalkers.json", function(response){
    var responseBody = "";

    response.on("data", function(dataChunk) {
      responseBody += dataChunk;
    });

    response.on("", function(){
        console.log(responseBody);
    });

});

request.on("error", function(error){
    console.error(error.message);
});

I believe it's looking for something like this. It says to concatenate the data stream to the responseBody variable, so when a response with data is sent, it will concatenate the dataChunk into the responseBody variable.
