It does if you are an absolute beginner to programming. If you are already seasoned then yes it doesn't add much, it just means you aren't the target audience.

Which the JOE folks make quite clear. Why would anyone assume this was not for complete novices new to programming in general? It seems odd to me.

I find it a very good start for someone new to programming with zero experience and wishing to start with elixir.

There are hardly any books that approach programming elixir from a complete lack of programming knowledge POV. I'm happy to see this!

Thank you for the validation! :) It really helps to see support like this for the project.

Aha, then add more fun through pictures (the drop of elixir thing at the homepage could be the spokesperson). How many people are working on this?
