Welcome to Kotlin Decoded, a series of articles where I share my notes on learning Kotlin as a Java developer.

These articles compare Kotlin and Java and provide useful tips from various sources. They can save you some time and clarify some concepts.

The articles are mainly for Java developers. But you may still learn something new if you come from another language. Just keep in mind that this series is not a comprehensive Kotlin tutorial and is not suitable for beginners without any prior programming experience.
