JavaScript Tutorial & Real JavaScript Projects

I ran/opened the html file. I have not used any of the other files yet.

Okay, after thinking about it and checking it line by line, I think it is very likely the problem is coming from Node. When I used it, at first it was not working, then after making it a absolute path, it did not output anything, now I have this, but I now remember that when Node was not working, it showed the message"Code language not supported or defined" a few times. I just need to know how to troubleshoot this.
