Cross-platform development is an attractive goal. Java enabled developers to write code that runs everywhere. However, it mostly targeted back-end development. Kotlin is a cross-platform programming language that targets mobile (Android and iOS), web, and back-end development. It provides all of these features with a familiar VM-based runtime and modern language features. In this course, you’ll learn the syntactical elements of Kotlin for working with variables, conditional statements, and loops. You’ll then learn about object-oriented programming and how to work with collections and generics in Kotlin. Finally, you will apply the skills from this course to develop a workout manager application. After completing this course, you’ll be able to create robust applications using a modern programming language. Since Kotlin is multi-paradigm, it’s easy to use. You’ll be able to use this Google-recommended programming language to develop both Android and iOS mobile applications.
