I haven&#x27;t hit their site yet, but I don&#x27;t think they&#x27;re saying you need Elixir to build this kind of project.  I think it&#x27;s more along the lines of needing Elixir to build a tutorial series for Elixir.<p>As for the benefits of using Elixir, I&#x27;m not qualified to answer that since I&#x27;ve only skimmed the surface of what Elixir is (but it looks intriguing!).
