Explore the foundational concepts of the functional core in Elixir development. Understand how to organize core business logic into modular functions that maintain a stable API, decoupled from process machinery like GenServers. Discover the balance between pure and impure functions and how this approach enhances testability and code clarity.

In this chapter, we’ll dive into the functional core, sometimes called the business logic of our component. Functional-core is the F for fun in "Do fun things with big loud worker-bees.” In the previous chapter, we worked with data. We carved our project into hollow modules holding structs that form our data skeleton. This chapter will fill those empty modules up with functions, each ...
