I mentioned that already, but I want to emphasize that you will not benefit from this course if you are a total programming newcomer.
On the other hand, you do not need to be a Kotlin expert with experience in DSL, or coroutines. I truly believe that with the way this course was built, understanding basic Kotlin concepts should be enough.
Also, I you haven’t worked with Kotlin, but have prior experience with other programming languages, especially JVM, then of course you will be able to benefit, too.
