11.5 Experimenting with Kotlin

When learning a new programming language, it is often useful to be able to enter and execute snippets of code. One of the best ways to do this with Kotlin is to use the Kotlin Playground (Figure 11-1) located at https://play.kotlinlang.org:

Figure 11-1

In addition to providing an environment in which Kotlin code may be quickly entered and executed, the playground also includes a set of examples and tutorials demonstrating key Kotlin features in action.
