About Elixir

Key Features of Elixir



Elixir is used for web development, embedded software, data ingestion, and multimedia processing.


Multi-clause functions with pattern matching and guards are the building blocks of Elixir code.

Dynamically typed

Elixir has no compile-time type checks, favoring run-time pattern matching.


All data in Elixir is immutable, allowing for safer and easier-to-reason-about concurrency.


Elixir uses the actor model - shared-nothing concurrency via message passing.

Fault tolerant

Elixir runs on the Erlang VM, known for running low-latency, distributed and fault-tolerant systems.

Get mentored the Elixir way

Every language has its own way of doing things. Elixir is no different. Our mentors will help you learn to think like a Elixir developer and how to write idiomatic code in Elixir. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in Elixir - they'll help you discover the things you don't know that you don't know.
