The Ubiquitous Language in Functional Programming
Please log in to watch this conference skillscast.
Domain modelling in software is never pure. Next to the domain data and business logic there is a whole other universe of programming language constructs that we have to deal with (control structures, error handling, asynchronous computations, etc).
In Functional Programming in general and in Scala in particular, we have many data types that model those general programming aspects. In DDD terms, you could say that they model the ubiquitous language of simple computations.
In this talk, you will explore and analyze a few well-known data types in Scala (Option, Either, Cats Validated, etc) and try to understand them from a Domain-Drive Design perspective. You will also discover some code samples to illustrate how they can be abused and how you can refactor them by creating new data types.
