## What it is
A collection of benchmarked Elixir code idioms comparing semantically equivalent approaches to show which is faster, inspired by fast-ruby. Each idiom includes runnable benchmark code using benchee.

## Use cases
- learn which elixir code patterns are faster
- benchmark map lookup vs pattern matching in elixir
- find faster alternatives to string concatenation in elixir
- compare ets vs gen server performance
- optimize slow elixir code
- learn elixir performance idioms

## When to choose
- you write Elixir and want to learn performance-oriented idioms with measured evidence
- you want runnable benchmark examples to adapt to your own codebase

## When to avoid
- you need a library to add to your project rather than reference material
- you need guaranteed up-to-date benchmarks for recent Elixir/OTP versions
- you work in a language other than Elixir

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: benchmarking, developer-tools
- domain: performance, programming-languages, tutorials
- platform: elixir
- tags: elixir, performance-optimization, idioms, benchee, benchmarks, fast-ruby-inspired, erlang-vm
