In this chapter, we were introduced to Kotlin and explored its fundamentals. In the process, we learned how to install Kotlin on a computer, what an IDE is, the IDEs at your disposal for writing programs in Kotlin, how to write and run Kotlin scripts, and how to use the REPL. In addition, we learned how to work with both IntelliJ IDEA and Android Studio, after which we implemented a simple Android application. Lastly, we had a look at the fundamental concepts related to the web.
In the next chapter, we will get more familiar with writing Kotlin programs by creating an Android application. We will take a look at the Android application architecture and the important components of an Android application, as well as many more topics.
