Summary

In this chapter, we took a look at the history of Kotlin and explained how it compiles to Java bytecode. Thanks to Kotlin's great interoperability with Java, we've seen that it has wide use cases, from Backend apps to Mobile and Desktop apps. We'll be using IntelliJ IDEA as our IDE in this book, as Kotlin is supported out of the box. Finally, we discussed build tools that support Kotlin.

In the next chapter, we'll start with exploring the language and learning the basics.
