What I like most about Elixir is how it offers developers a very stable foundation to build upon, both in terms of technological stability (thanks to BEAM) and in terms of churn. With the release of Elixir 1.9 back in 2019, José Valim noted that Elixir was more or less “done” in terms of major features, and that the focus going forward would be on developer experience, ergonomics and other quality-of-life matters.
Not needing to chase new language features or to keep up with a whirlwind of changes allows me to focus on being productive. It also feels like much of the community has embraced a similar approach to libraries: they can actually be “done”, and you can rely on them for years.
This doesn’t mean the ecosystem or language would be stagnating, however. Just a few weeks ago, the Erlang team released OTP 24 that adds, among other things, a just-in-time compiler that greatly boosts the performance of code running on BEAM. Depending on your benchmark, you can expect a performance improvement between 20% and 60%, which is massive. And yet, as an Elixir developer, I don’t have to do anything to reap these benefits. This is the kind of enhancement of a language I truly appreciate.
