Functional Design

Capture the benefits of functional programming techniques across your whole application, in a way that's highly accessible to the whole team and new hires.

Most problems can benefit from a domain-specific model, constructed using immutable data types and operators. Functional Design teaches you how to directly benefit from functional programming techniques across your whole application, in a way that's highly accessible to the whole team and new hires — without requiring knowledge of category theory or type classes.
