Imperative, declarative, object oriented, functional: four of a Kotlin kind
summary
Kotlin demonstrates concrete support for all four paradigms and recommends using each where it fits: imperative uses mutability, nullability, if-as-expression and loops; declarative shows Jetpack Compose and a DSL using extension-lambda on Card to build UI/config; object oriented relies on data classes, delegates, default and named params; functional uses lambdas, chainable operations (filter/map/reduce) to chain filter map sum for Joker points, monad-style wrappers for errors and tailrec prevents stack overflow with compiled Java output shown.
