I wish Treehouse would redo this course with Guil. His courses are so clear and well put together.

Agreed! Very hard to follow.

The explanations are good, but this course needs more practice problems. If you don't apply the concepts enough, all the information will just go in one ear and out the other.

If you're looking for extra practice, The Odin Project has a course on Node that's free.

Yeah pretty much every course with Chalkers really makes me hesitate.

so they want you to add "end" to the response function. 

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

so your completed code will look like this. 

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

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

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

});

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

I notice two syntax errors in your code:

The first one is in this line:

responseBody += dataChunk; });

The callback and function is closed on the line below so the last couple of characters "});" do not belong on that line.

The second is in this line:

response.on("end", (function) () {

The parenthesis wrapping the function keyword is invalid, they should not be there.

If you remove the unnecessary characters and the parenthesis I pointed out above then your code should work.
