About Erlang

Erlang is a functional programming language, used for creating real-time distributed systems, which can easily scale in size.

It's best for concurrent applications, such as instant messaging and banking platforms, as each function call has their own process and operates independently. This is useful as code can run for a very long time without issues occuring. Also, processes and message passing are all built into the language by default - no need for any extra libraries!

It was designed within Ericsson, a Swedish telecommunications company, for use in their networks, and is currently used inside telecommunication equipment.

-module(example).
-export([hello/0, test_version/0]).

hello() ->
  "Hello, World!".

test_version() ->
  2.

Exercism is a great website

Exercism is a great website where I was able to have some very interesting challenges.

Relaxed. Encouraging. Supportive.

I'm a software engineer. I develop high load systems with erlang/otp and elixir. Also I have experience with ruby and some other programming languages.

I got into erlang because elixir was not available at my university. I have not yet been able to work professionally with it, but used it for personal tools some times.
Fun. Challenging. Interesting

Meet the Erlang Track maintainers

The Erlang Maintainers are the brains behind the Erlang Track. They spend their spare time creating interesting and challenging exercises that we can all learn from. We are incredibly grateful for their hard work. Here are the bios of a few of the maintainers of this track.

Found out about erlang via exercism, got hooked by its lightweight processes and how they are used as first class citizen. After fixing some trivial bugs in the track, I have been added to the team.

Get started with the Erlang track. As with everything on Exercism, it's 100% free!
