ABOUT THIS COURSE
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.

These are high-quality courses. Trust me the price is worth it for the content quality. Educative came at the right time in my career. I'm understanding topics better than with any book or online video tutorial I've done. Truly made for developers. Thanks

You guys are the gold standard of crash-courses... Narrow enough that it doesn't need years of study or a full blown book to get the gist, but broad enough that an afternoon of Googling doesn't cut it.
