Читать книгу Programming Kotlin Applications - Бретт Мак-Лахлин, Brett McLaughlin - Страница 68

The title of this chapter is “It's Hard to Break Kotlin,” which may seem like the opposite of what you're seeing. Without much effort, you've managed to get Kotlin to throw a lot of different errors, and Kotlin seems quite resistant to helping you out with converting between types.

That said, Kotlin is actually breaking before your code is running in some production system, serving an API for a mobile app, or running on a phone or just handling web requests. In other words, Kotlin is making you do some extra work at compile time—when you're writing code—to avoid potential problems when the program is running and needs to work.

Put another way, the chapter might be better titled, “It's Hard to Break Kotlin When It's Running in Production Because It's Going to Make You Be Really Specific about Types When You're Writing that Code Before It Gets to Production.” Of course, that's really not a title that anyone is going to let get through editing and proofing, so let's go with “It's Hard to Break Kotlin” and trust that you know what that really means.
