About this course

Many developers struggle to understand how Elixir processes and builds collections under the hood. By mastering Elixir's protocol system, you can write cleaner, more idiomatic code that handles data pipelines with ease. This text-based course guides you through the inner workings of Elixir collections, focusing on how the Collectable protocol enables efficient data insertion. You will transition from writing manual loops to leveraging Elixir's native collection-building power. What you'll learn: - Understand the core concepts of Elixir protocols and how they enable polymorphism - Implement the Collectable protocol to build custom, reusable collection types - Apply Enum.into to streamline data transformation pipelines - Practice pattern matching and recursion to manipulate collection elements - Explore modern Elixir stream processing for memory-efficient data loading - Configure typespecs to ensure robust and type-safe collection operations You will start with foundational definitions of protocols and collections before moving on to practical, step-by-step written exercises. The course walks you through real-world scenarios, demonstrating how to integrate these concepts into your everyday Elixir development. This course is designed for beginner to intermediate Elixir developers who want to deepen their understanding of functional data structures. No prior experience with custom protocols is required.
