Part 3. Domain-driven design

This part takes us to the land of domain modeling with embedded domain-specific languages. We start by exploring the pivotal role of abstractions in DSLs, which not only prevent software bugs but also facilitate a deeper understanding of the domain by allowing only correct operations. This section emphasizes the significance of statically typed languages with robust type systems in developing safe, robust programs, positioning domain-specific languages as a core component in domain-driven design. We dive deep into the complexities of designing effective DSLs, the importance of algebraic data types (ADTs) in creating clear, reliable domain-specific languages, and the effective organization of embedded DSLs to enhance application design.
