Introduction to Scala by Piotr Wiśniowski Scalac
- 1. Into the Functional Programming Paradigm with Scala Piotr Wiśniowski Scalac
- 2. Piotr Wiśniowski Data Engineer at Scalac with a scientific background. Interested in: ● the newest algorithms, ● solving tough problems, ● architecture solutions Also, an avid traveler, hiking fan and sailor.
- 3. Scalac ● Backend / Architecture ● Frontend / User Interface ● Devops / Infrastructure ● Data Engineering / Data Science ● Quality Assurance ● Project Management
- 5. 1st stage: ● 3 days of basic tools training ● May 2nd Stage: ● 2 months of working on real project ● Summer time 3th Stage: Welcome to Scalac!!!
- 6. Scalac Summer Camp Details soon on: ● https://www.facebook.com/scalac.io ● https://twitter.com/scalac_io ● recruitment@scalac.io
- 8. Why Go Functional? ● Avoid confusing corner cases ● Avoid code errors ● Data processing ● Concurrent processing ● High-critically systems ● Not hard or difficult! ● Test-driven development
- 9. Functional programming You already know it!
- 10. You already know it!
- 18. Benefits ● No state! ● Invert control - caller always have control over callee ● Test applications easily ● Read programs easily ● Refactor code without changing meaning or behavior ● Reason about program by using types
- 19. You lose nothing from OOP ● Single responsibility ● Open-closed ● Substitutability ● Interface segregation ● Dependency inversion
- 20. Code examples
- 27. What is next?
- 28. Future reading ● John De Goes - FP to the Max video https://www.youtube.com/watch?v=sxudIMiOo68&t=1664s ● Learn libraries like Cats or Scalaz https://typelevel.org/cats-effect/api/cats/effect/IO.html ● Monads, Comonads, Profunctors, Operads, Fibrations etc.
