Rangesīefore you dive into the for loop statement, you need to know about the range data types, which let you represent a sequence of countable integers.

They’re incredibly powerful when used with argument matching. They let you inspect a value and decide what to do based on that value. You’ll also learn about when expressions, which are particularly powerful in Kotlin. Or if you have a game with multiple computer-controlled characters, you might need a loop to go through each one and make sure it knows what to do next. For example, you might have code to download an image from the cloud with a loop, you could run that multiple times to download your entire photo library. Loops may not sound very interesting, but they’re very common in computer programs. You’ll learn about another loop known as the for loop. In this chapter, you’ll continue to learn how to control the flow of execution. In the previous chapter, you learned how to control the flow of execution using the decision-making powers of if expressions and the while loop.
