- 16. Whats happy with FP • Concurrency • Scalability
- 17. Imperative vs Functional • Imperative Programming do A -> state++, do B -> state++, ... • Functional programming in1 -> f(x) -> out1 in2 -> g(x) -> out2
- 18. + concurrency
- 19. Easy concurrency • Imperative programming do A -> state <- do B > sudden conflict!!! < • Functional programming in1 -> f(x) -> out1, in2 -> g(x) -> out2 > no conflict!!! <
- 20. Easy scalability • Single Play req -> acion1(x) -> result req -> acion2(x) -> result ... • Multiple Play’s req -> play1 -> result req -> play2 -> result ...
