Is Erlang similar to Java?
Erlang and Java are similar in the sense that both use a virtual machine to abstract the hardware into a portable layer. Both languages employ machine independent byte code. Both run-time systems rely on garbage collection to free the programmer of doing memory management. Threading overhead in Erlang is very low.

Messaging apps, including some famous examples like WeChat and WhatsApp, use Erlang to handle insane amounts of concurrent users.
Is Erlang the only language that uses beam?
Erlang isn’t the only language that operates on BEAM; there are multiple others. The main one is Elixir. What is Elixir? Elixir was created by José Valim in the early 2010s. He took Erlang and made a thin layer on top of it that had a more modern syntax that resembled Ruby. The resulting language was an improvement over both Erlang and Ruby.
