Pro Android with Kotlin

The programs explained in this book, despite their strong affinity to the Kotlin way of thinking, will not be totally mysterious to Java developers or developers of other modern computer languages. One of the design goals of Kotlin is expressiveness, so understanding Kotlin programs requires little effort, even when the programs get shorter. But at some point, you have to pay for maximum brevity with a loss of expressiveness and a loss of readability. When it comes to deciding what is better, I favor expressiveness over brevity, but be assured that a loquacious programming style is a no-go. In the end, professional developers want to write concise apps because less code means lower costs when it comes to maintenance.
