Implement encoding and decoding for the rail fence cipher.
Multi-clause functions with pattern matching and guards are the building blocks of Erlang code.
Erlang has no compile-time type checks, favoring run-time pattern matching.
All data in Erlang is immutable, allowing for safer and easier-to-reason-about concurrency.
Erlang uses the actor model - shared-nothing concurrency via message passing.
Erlang runs in a VM known for running low-latency, distributed and fault-tolerant systems.
Can pull in both Erlang and Elixir packages, both public and private
Every language has its own way of doing things. Erlang is no different. Our mentors will help you learn to think like a Erlang developer and how to write idiomatic code in Erlang. 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 Erlang - they'll help you discover the things you don't know that you don't know.
