The Best Kotlin online courses and tutorials for beginners to learn Kotlin programming language in 2020.

The Kotlin programming language is a modern language that gives you more power for your everyday tasks. Kotlin is concise, safe, pragmatic, and focused on interoperability with Java code. It can be used almost everywhere Java is used today: for server-side development, Android apps, and much more. Kotlin is 100% compatible with all existing Java frameworks and has good tooling support.

It is a pragmatic language with a very low learning curve and can be quickly grasped by Java developers. Kotlin code might be compiled not only to JVM bytecode but to JavaScript and Native code as well.

Kotlin is quickly joining the ranks of the most popular programming languages. Now that Google supports Kotlin for Android app development as the primary choice over Java, you will only see more developers making the switch. So if you are looking to get started with Android app development, then you should learn this language.
