I loved the way the book "Kotlin in action" explains things, not only as a reference but as a way to go back to when I can write some code but not sure about some details.
• Is there plans to make a new edition for coroutines?
• is there a different book that covers coroutines?
The official docs and the official / unoficcial blog posts are good, but they can't replace a good book for some situations.
