Elixir

Join the Elixir Track
Elixir is a dynamic, functional language designed for building scalable and maintainable applications. Elixir leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems, while also being successfully used in web development and the embedded software domain.

About Elixir

Elixir, initially released in 2012, extends upon the already robust features of Erlang while also being easier for beginners to access, read, test, and write.

José Valim, the creator of Elixir, explains here how he built the language for applications to be:

  1. Distributed
  2. Fault-Tolerant
  3. Soft-Real-Time
  4. Hot-Code-Swapped (can introduce new code without stopping the server)

Elixir actually compiles down to bytecode and then runs on the BEAM Erlang Virtual Machine.

There is no "conversion cost" for calling Erlang, meaning you can run Erlang code right next to Elixir code.

Being a functional language, everything in Elixir is an expression.

Elixir has "First Class Documentation" meaning comments can be attached to a function, making it easier to retrieve.

Regular expressions are also given first class treatment, removing awkward escaping within strings.

Elixir's asynchronous communication implementation allows the code to be lightweight, yet incorporate high-volume concurrency.

Programmers use Elixir to handle thousands of requests and responses concurrently on a single server node.

It has been used successfully for microservices that need to consume and serve a multitude of APIs rapidly.

The Phoenix framework helps structure Elixir applications for the web.

Self-contained finite problems with which to learn the language

I have spent time with the Clojure, Elixir & Go tracks and all have been incredibly beneficial, providing self-contained finite problems with which to learn the language. The Go language track has been wonderful in introducing me to the language, what idiomatic code is, and the many different ways in which one can solve a problem.

Relaxed. Encouraging. Supportive.

I am a cheerful guy who really enjoys programming, speaking and extending knowledge. I have been working commercially with Elixir since March 2017. I am thrilled to help.

I am happy to help. I have been working professionally in Elixir since January 2018 and have presented at Empex, ElixirDaze, and ElixirConf 2018.

The syntax is slightly ruby-ish and quite easy to grasp. But it truly is stading on the shoulders of giants (Erlang / OTP) which makes it my go to language for most new projects.

I have had an interest in functional programming for years, and Elixir has been my outlet for a while now. I love being able to program without hidden side effects, and I love the way functional programming changes the way you think about program flow.

I first got into Elixir in 2015 and haven't looked back. My day job still largely centres around .NET but Elixir is the language I remain the most passionate and excited about.

I found about elixir on exercism and thaught it were just another ruby, dropped it because I haven't had classes, read more about it, felt in love and cut off my relationship with ruby (nearly).
Fun. Challenging. Interesting
