Kotlin Development

Kotlin is an object-oriented language that can run equally well on the Java Virtual Machine or natively on the operating system. Kotlin is also a functional language, and combines the features and benefits of OO and functional programming. This course provides a fast-paced introduction to the language for developers with experience Java or similar languages (e.g., C# or C++), and then delves deeper into idiomatic uses of Kotlin in practice. The course also shows how to use Kotlin Multiplatform to implement a common codebase that can run on any platform.

«The instructor was really good, and he came prepared every day. He also seemed to have a very high level of expertise in the programming language he was teaching, which was Kotlin. He could answer all questions no matter how hard and complex the questions was. He also had a nice and understandable way of explaining advanced subjects. » Cato Hilmi Akay, Skatteetaten
