Describe your suggestion

With this Issue I will list the lessons in the Organizing Your JavaScript Code section that I've identified as having lint errors and need fixing.

The lessons in this section with lint errors:

• ES6 Modules
• JSON
• Factory Functions and the Module Pattern
• Project: Library

Most of the problems in these lessons are formatting and missing note-box heading issues, so should be fairly straightforward to fix.
I'll start the work and submit a PR fixing these issues as soon as I'm assigned.
