Scala: Advanced Functional Programming Training Course
Description
Scala is a concise, object-oriented language with functional programming features, including currying, type inference, immutability, lazy evaluation, and pattern matching.
In this instructor-led, live training participants will learn how to use Scala’s advanced features to develop well-constructed software that is easy to write, read, test, and change. The focus of this training is on functional programming, using real-world case studies and discussion as a reference for lab exercises and activities.
By the end of this training, participants will be able to:
- Implement advanced functional programming techniques
- Make sense of complex type signatures
- Understand code through types and substitution
- Handle exceptions functionally
- Create libraries and DSLs with Scala
- Use Scala’s advanced features for pattern matching
Format of the course
- Part lecture, part discussion, exercises and heavy hands-on practice
