22: Ruby to Elixir

This episode compares and contrasts the programming languages Ruby and Elixir, focusing on Elixir's features and benefits. The podcast begins with a "workout of the week" segment, then provides an overview of Elixir, highlighting its functional programming nature, immutability, and concurrency features built upon the Erlang virtual machine. Key differences discussed include Elixir's `mix` (vs. Ruby's `rake`), file extensions (.ex, .exs), macros, IEX (interactive Elixir shell), and automatic code formatting. The speaker emphasizes Elixir's advantages in testing, concurrency, and hot code swapping, recommending resources like Pragmatic Studio videos and the Elixir getting started guide for further learning.
