I've also used CodePen for the freeCodeCamp curriculum. I wrote all of my code in a text editor, and when I had completed it, I copied it into CodePen and referenced the file with the user stories. If my code did not fulfill the requirements, I edited the code in the text editor and then copied it back into CodePen. It was easy to save the completed code and copy a link to the freeCodeCamp project.
