Overview
Kotlin is one of the most promising JVM languages and has seen immense growth over the last few years. The language is now being used in thousands of systems, including both backend and frontend. Kotlin is a multiplatform JVM language that was announced as the official programming language for Android by Google some years ago.
This course is designed for developers who want to grasp the language, so they can work with any Kotlin projects professionally.
Why Kotlin?
- Concise: Drastically reduce the amount of boilerplate code.
- Safe: Avoid entire classes of errors such as null pointer exceptions.
- Interoperable: Leverage existing libraries for the JVM, Android, and the browser.
- Multiplatform: Supporting JVM, iOS, Android, JS, Linux, Windows, Mac, and even embedded systems.
- Tool-friendly: Choose any Java IDE or build from the command line.
Prerequisites
- One year of experience with any object-oriented or JVM language.
- Desirable: some IntelliJ IDEA experience.
