Is Erlang difficult?
TL;DR Not really more difficult than any other language. It has its unique features and challenges. The most important thing is learning to think concurrently. It’s fun — do it (or learn Elixir instead)!
Is it worth to learn Erlang?

Does Erlang run on JVM?
It is no surprise that floating point operations on Erjang, the version of Erlang running on the JVM, was 5000\% faster than the BEAM.
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.

What can you do with Erlang?
Primarily, Erlang is a good choice whenever messaging between multiple agents across the network is involved, since that maps well on the basic structure of the language. Chat apps. 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.
Should I use Erlang for fintech projects?
If you need to process transactions coming from a ton of places in your fintech project or create a bidding/user matching platform, Erlang is not the worst choice either. You can check out some of the frequent use cases of Erlang in our list of Elixir and Erlang companies. This looks complicated. Can I build a web app in Erlang? Yes.
