One thing the author didn't mention is how incredibly polished the primary ecosystem of documentation, standard library, and tooling is. The Elixir standard library is incredibly consistent in order to support Elixir's piping operator, such that the first argument will basically always be the information you want passed from the function before it. In comparison, I frequently have to check the docs to confirm argument order on any lesser-used function in Python, Javascript, or C#. Then there's the fact that the second-layer of standard library, the OTP inherited from Erlang, which is expansive to the point of containing most things you'd want to do on a server. The documentation, in turn, is the gold standard that I (typically negatively) compare all other language docs to. It's organized, discoverable, and covers not just the "what" but the "How" and "Why" exceptionally well, not just at the function level, but the module layer as well. Frankly, only MDN comes close. All combined, it's just an incredibly productive language.
