  1. Learn how to ask questions well. This is an important part of being a dev. Often, at work when I have to figure out how to ask a question, the process of figuring out how to articulate it will give me a deeper understanding of the problem, and sometimes will help me figure it out.
  2. Recursion is a difficult subject. There are many, many threads on here about it and about this problem specifically.
  3. Your code is almost there. I just needed to change one small thing. Learn how to debug. Debugging is about being a detective. Gather data. Put a console.log(n) at the beginning of the function. What is happening to n? What would we expect to happen?
