Programming Elixir

A comprehensive guide to functional and concurrent programming using Elixir. It covers the transition from object-oriented to functional thinking, pattern matching, immutability, the actor model for concurrency, and building robust distributed systems with OTP.

Master the art of building resilient, concurrent systems through the beauty of functional programming.

1. Contrast the data transformation model of Elixir with conventional state-based programming.
2. Configure the interactive Elixir shell (IEx) and execute Elixir code via scripts and compilation.
3. Apply the match operator (=), pin operator (^), and wildcard (_) to destructure and validate data.
4. Explain the theoretical and practical implications of immutability on performance and memory management.
5. Identify and utilize Elixir's built-in types, including Value, System, and Collection types.
6. Apply variable scoping rules and the with expression to manage complex data transformations.
7. Create and invoke anonymous functions using both standard and capture (&) notation.
8. Implement named functions within modules using pattern matching and recursion to handle complex logic.
9. Apply guard clauses and default parameters to control function execution flow.
10. Deconstruct and Construct Lists: Use head/tail pattern matching to navigate and build recursive list structures.
