cant figure out whats wrong that does not really tell a lot about what the problem is - you might want to describe what problem you're experiencing + what error message you're getting? :-)

A few people have mentioned getting errors using the string literal `` and using the format username.json. One other forum question recommended formatting the request string literal like this:

const request = https.get(`https://teamtreehouse.com/${username}?format=json`,  ...

Going in your browser, both username.json and username?format=json in the URL work and return the correct JSON object.

Changing your string literal to ?format=json may fix the issue but I'm not sure why. Anyone?

Can you describe what issue you are having? But just from looking at the code it may seem that your url in https.get is not using proper quotes.
