  1. Mediator Examples: Phoenix Controller, Phx LiveView Solutions:

    • Funcs and modules for controlling and coordinating logic
    • Processes for controlling and coordinating events

  2. Facade Examples: Phx Contexts, Logger, Elixir compiler Solutions: Modules prociding a simplified API to the more general facilities of a subsystem

  3. Strategy Examples: Solutions:

    • Pattenr matching
    • Anon functions
    • Interfaces from OO a.k.a Protocols in Elixir -- interfaces are a mechanism for polymorphism (with upfront contract)"(c) José Valim Polymorphism in Elixir: Behaviour == Modules State == Data Mutability == Processes

    "Favor object composition over class inheritance"(c) Gang of Four
