Elixir is the thing I do most of my public writing and speaking about. It is my default programming language for the last 5-6 years. It suits my brain. Performs well for the kind of work I typically do. And using it I have experienced very few drawbacks. Rather than writing yet another post trying to widely summarize what I think is beneficial about the language I want to try and go a bit deeper on one particular aspect I like. Not incredibly technically deep, but unpack the concepts more thoroughly. I hope this will be a series of stand-alone posts. We will see. This time we unpack Elixir concurrency (and parallelism).
