Kotlin Advanced

Ready to master advanced Kotlin techniques? Learn operator overloading, generics, reflection, DSL construction, and more to build clean, powerful APIs and applications.

Description

Developers with foundational Kotlin knowledge advance their skills with powerful language features. This course builds upon basic Kotlin knowledge, diving deep into advanced topics that enable you to write more expressive, type-safe, and elegant code.

You will learn advanced Kotlin features through practical examples and hands-on exercises. Topics include operator overloading, higher-order functions, generics with variance, annotations and reflection, and building internal DSLs. This course follows the training "Kotlin Fundamentals" and covers chapters 7-11 from "Kotlin in Action".
