Functional Concepts in Elixir
summary
Shows concrete Elixir code patterns: using pattern matching for authentication and extracting current_user_id, modeling data with maps and binaries, and passing anonymous functions into Enum and Stream. Demonstrates tail recursion with an accumulator to process millions of items without stack growth, a simple continuation‑passing style workflow integrated into a supervisor/OTP process tree, and argues that referential transparency and pure functions make testing and reasoning about stateful apps easier.
