COURSES INCLUDED

Getting Started with Kotlin
Since 2019 Kotlin has been designated as the official programming language for Android development. However, Kotlin can be used for more than just mobile application development. Kotlin supports server-side development, full-stack development, data science, native application development, and multiplatform development. Kotlin compiles to Java bytecode, runs on the Java Virtual Machine, and can interoperate with existing Java code in your projects. In this course, you will be introduced to the Kotlin programming language. You will discover various use cases for Kotlin and identify when you would choose to use Kotlin over Java. You will use the Kotlin online playground to write your first bit of code, run Kotlin on the Java Virtual Machine (JVM), and compile Kotlin code to JavaScript. Next, you will use the Kotlin command line compiler on your local machine and run the Kotlin REPL (read-evaluate-print-loop) interactive environment to work with Kotlin code. Finally, you will install the IntelliJ integrated development environment to work with Kotlin and create and run your first Kotlin project.
