What is the right way?

How do you get the right responce?

app.js 
const https = require("https");
const request = https.get("https://teamtreehouse.com/chalkers.json", response => {
    let responseBody = "";

    response.on("data", dataChunk => {

    });

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

});

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

The challenge is asking you to "... modify the data callback to concatenate the stream of data to the responseBody." So that means you would add code to the blank line provided after "response.on("data", dataChunk => {", which is the body of the "data callback".

And you can concatenate the "dataChunk" to the existing "responseBody" with the "+=" operator.

I'll bet you can get it now, but write again if you still have trouble.
