Trying to make Scala better for "simple" projects is definitely a focus of this book. You are right that traditionally the fixed overhead of learning Scala made it only worth it for huge and complex projects, but this book introduces it in a way that's easy to learn and easy to get started with, making it feasible to use for tiny projects 1 line of code and above. In particular, none of the projects in this book take more than ~2 pages of text (~90 lines). You implement a programming language in <90 lines, a real-time network file synchronizer in <90 lines, a websocket chat website in <90 lines, a massively-parallel web crawler in <90 lines. These are 90 line complete applications, not "90 lines changed in a sea of boilerplate" or some other nonsense like that! The goal of all this is to make a case that yes, you can use Scala for small projects! But you'll have to read the book to see for yourself if you find it convincing :)
