8. Why Kotlin?
   We think of Kotlin as a modern language for industry: it is focused on flexible
   abstractions for code reuse and readability, static type safety for early error
   detection and explicit capturing of intent for maintainability and clarity.
   One of the most important use cases for Kotlin is a big Java codebase whose
   developers want a better language: you can mix Java and Kotlin freely and
   migration can be gradual and doesn’t have to alter entire codebase. (link)
   —Andrey Breslav, Lead Language Designer of Kotlin at JetBrains
