A good idea for self-learning too. However where are your articles in the repo? Or did I misunderstand that. Are you writing articles about each concept or linking them?
If I would write every article for each concept, it would take a lot of time and research too, and I don't think I would be able to explain each concept better than some guys out there.
We have a lot of people that are really good JavaScript developers, so there's no need to write every article about each concept.
