Scala Cookbook: http://shop.oreilly.com/product/0636920026914.do (most of it is available online here: http://scalacookbook.com/) Once you are done with this, you can pretty much pick any of the projects here and start reading the source code: https://github.com/lauris/awesome-scala https://github.com/adamw/awesome-scala Reading code is the probably the best way to learn any programming language IMO

I can't disagree more about immature ecosystem. Cats, Scala.js, Shapeless, Akka, reactive streams (Akka Streams, Monix, etc.), Play, Slick and other awesome libs [1] are one of the main reasons why I am using Scala at all. IntelliJ Scala plugin is not perfect, but it understands code much better than, for example, Clion or QtCreator without clang code model, and C++ ecosystem is hardly immature, and of course it's lightyears better than any dynamic language IDE support. Code complexity though, yeah, it's hard (for me, at least) to grasp ordinary for Scala abstraction-heavy, typeclass-heavy code. I would love to see better code exploration tools for Scala.
