What can BEAM do that other languages can't? Do you have a favorite learning resource for it?
"The Soul of Erlang and Elixir by Sasa Juric"
Really one of the best presentations to show what you may get out of adopting Elixir.
It's not so much that it does things others can't, it's that it does all the things, running in the same application space, and things like background jobs, or a caching layer, or cron are all things that most stacks these days need to sort via another library, and Erlang/Elixir apps just do it all on BEAM.
