- Elixir docs are top notch, both the existing docs for the language and its ecosystem, and the ease of generating your own docs for your projects and libraries.
- The only thing that is not currently top notch in Elixir is the Language Server and therefore IDE support. This will hopefully improve soon after the formation of an official Language Server team to unify previously disparate efforts (https://elixir-lang.org/blog/2024/08/15/welcome-elixir-langu...).
I mention the Language Server and IDE support because, IMO, it is the biggest __technical__ hurdle preventing widespread adoption. If you’re considering learning Elixir, I think now is a great time!
