A modern programming language that makes developers happier.

kotlinlang

*Good morning, I'm searching for any kind of resources ( book, courses, exercises, etc ) for learn Kotlin for a total beginner.*

I'm trying to introduce this awesome world to my girlfriend, but everything I found is bases on a preexisting Java knowledge. 

I know it would be better to know the programming basics ( the hardware, algorithms, data structures, concurrency, etc ) but on the other side I'm also a self learner and I skipped some basics concepts that I learned in a second time and sometimes, when starting to learn, the satisfaction to implement a timeout with a simple `withTimeout` is more important than the frustration in learning to use threads in Java
