Overview

Many Scala developers are comfortable working with immutable data, pattern matching, and recursion. Yet beyond these introductory topics lies many more powerful concepts and techniques from functional Scala, which together enable the construction of powerful and type-safe applications that could not be written in Java or other non-functional languages.

In this course, developers will learn select topics from Functional Data Modeling, Functional Design, and Functional Effects. This trio of topics, covered at high-speed and with extreme focus, will help Scala developers who already know basic functional programming to take their knowledge and skills to the next level, as they see first-hand how functional Scala enables them to write better code, with high productivity and testability.

Who Should Attend

Scala developers who would like to apply functional programming to more of their code base, or begin using functional Scala libraries.

Prerequisites

Good working knowledge of Scala, including familiarity with immutable data, pattern matching, and basic recursion. Developers who have attended Functional Scala Foundations will be well-prepared for this course.

Topics

• Polymorphism in functional data modeling
• Using generalized algebraic data types for increased type-safety
• Using declaration-site variance for better ergonomics
• Extracting domain elements and operators from business problems
• Designing composable, orthogonal, minimal operators
• Translating domain solutions into general solutions
• Describing side-effects with values
• Using functional programming “in the large” over a whole app
• Leveraging functional effects for increased productivity
