## TL;DR

Elixir (José Valim, 2011) is a dynamic, functional language built on the Erlang VM (BEAM) — inheriting Erlang's fault tolerance, concurrency, and distributed computing capabilities. Used by: Discord, WhatsApp (Erlang), Bleacher Report, PepsiCo. Phoenix Framework for web, Nerves for embedded.

## Core Explanation

Actors: lightweight processes (not OS threads) communicate via messages. `receive` blocks match incoming messages. `Task.async/await` for concurrency. Pattern matching is fundamental: `=` is match, not assignment. Pipe operator: `|>` chains function calls. Phoenix LiveView: real-time server-rendered UI without JavaScript. OTP (Open Telecom Platform): battle-tested patterns (GenServer, Supervisor).
