Notes and projects for my book, “Functional Programming, Simplified"
Hi Alvin, on page 119 shouldn't it read _"Pure FP Code is more strict than EOP, FP is a subset (instead of superset) of EOP"_? On page 122 I would...
``` val evenOrOdd = i match { case 1 | 3 | 5 | 7 | 9 => println("odd") case 2 | 4 | 6 | 8 | 10 =>...

``` As a fun example of some things you can do with PAFs, the [“partially-applied func- tions” section of the Scala Exercises website](https://www.scala-exercises.org/koans#partiallyappliedfunctions) demonstrates that you can create curried functions...
