The step-by-step explanations make it accessible for both beginners and intermediate users.
What stands out most is the practical approach, with clear examples that are directly applicable to real-world scenarios. The authors’ insights and best practices are particularly helpful for writing clean and efficient Kotlin code.
Overall, this book is a must-read for anyone serious about mastering Kotlin. I highly recommend it and would rate it 5 out of 5 stars.
Book allow deep in the Kotlin language. Describe simple issues and solve them. Book helped me transfer from Scala language. As surprise kotlin features are allow use already known frameworks and just write Android applications.
