I was using freecodecamp’s tutorial on Kotlin but I was told that a video isn’t a good way to learn a language. So I did the hyperskill course but it marks all of my answers as wrong even when the code works, and the subscription for more than ten questions a day is crazy expensive. I will be getting atomic kotlin soon but I still want to learn before it comes
The official Kotlin Koans from Jetbrains are what I recommend, especially if you’re already familiar with Java.
