I don't have a CS background, so I can't speak much to the performance of Elixir and Crystal. As someone who has made the transition from Ruby to Elixir, I'm really, really intrigued by Crystal. Though, upon a cursory look into the Crystal docs and community, a couple things are clear... Elixir killed it on all the things surrounding the language. - docs - testing - Slack chan, IRC, mailing list - package manager (Hex) - build tool (Mix) - web framework (plug & Phoenix) - books from major publishers (manning, pragprog, etc.) - ElixirConf - ancillary teaching (ElixirSips, LearnElixir, Elixir Fountain, etc.) While the language may not be as computationally performant as some of others mentioned, all the things above lower the barrier to entry for adoption and make Elixir a more attractive language than some of the counterparts. And it's amazing that a language this young has nailed it on these fronts.
