## What it is
Elixir Koans is a collection of fill-in-the-blank exercises that teach the Elixir programming language through failing tests that learners make pass. It runs via a mix task with an autorunner that gives instant feedback as you edit.

## Use cases
- learn elixir from scratch
- practice elixir pattern matching
- hands-on elixir tutorial exercises
- refresh knowledge of elixir idioms
- teach a team the basics of elixir

## When to choose
- you are new to Elixir and want an interactive, test-driven introduction
- you prefer learning by fixing failing examples rather than reading docs
- you want a lightweight, self-paced tour of core Elixir features

## When to avoid
- you need a comprehensive reference or production-grade Elixir codebase
- you already know Elixir and want advanced or OTP-specific deep dives
- you want a video or guided course format rather than exercises

## Facets
- artifact type: learning-resource
- maturity: active
- function: testing, developer-tools
- domain: programming-languages, education, tutorials
- platform: elixir, cross-platform, cli
- tags: koans, elixir, learning-exercises, tdd-style-learning, mix-tasks
