Gain hands-on experience working with processing collections and utilizing Elixir's concepts to build robust applications.

Test Your Web Applications with Elixir

Elixir offers a practical approach to functional programming, emphasizing immutable state and leveraging the extensive range of packages, modules, and tools available in Erlang. In this module, we will gain hands-on experience working with Elixir, covering topics such as processing collections and control flows. With a focus on practical learning, this module provides abundant coding examples to strengthen our proficiency in Elixir and ensure a solid understanding of the language.
