Functional Object-Oriented Imperative Scala

Scala combines several paradigms, among which object-orientation, functional programming, and imperative programming. It is often tempting to use Scala as either a “better Java”, using object-orientation with less boilerplate, or a “worse Haskell”, focusing on purely functional code. In this talk, I present a style of writing “boring” Scala that embraces and advantageously combines all of said paradigms, in a simple way. We use functional code as a default, but do not hesitate to use mutability if it simplifies the code, and structure modular components using object-orientation.

Target audience

Beginner: No need to have prior knowledge

Who is your session intended to

Users who want to learn about a coding "style" for Scala that combines several of its main paradigms. This is how I write Scala every day, and the style I would generally recommend. Well-suited for beginners and experts alike.
