a Guided Introduction to Elixir - Part 3 of 6
summary
Guided code shows a concrete rock-paper-scissors exercise implemented with a map-based rule set and a simple REPL demo that actually prints results. The session uses Elixir primitives like spawn/send/receive mailbox to create a child process that sends a tuple and the parent process receives and pattern matches it. Notes call out using Enum/index functions not structs and suggest extending rulesets and nonblocking receive clauses; working examples are shown live.
