Practical Advanced Kotlin in Practice
summary
Hands-on workshop that requires cloning a Git repo, IntelliJ or Android Studio and aims to get unit tests green across exercises; covers practical Kotlin features with concrete tradeoffs: lateinit vs delegated notNull, lazy is synchronized by default (use NONE for speed), and reified inline functions to avoid passing Class objects. Also demos sealed classes, extension functions' JVM translation to static methods, DSLs and collection sequences, and gives actionable rules (avoid overusing delegates, lazy, operator overloads) rather than abstract theory.
