Kotlin

Kotlin is a modern, secure and statically typed programming language developed by Jetbrains, the company that also developed IntelliJ IDEA.

It is a great programming language to learn because it is simple and easy to understand. It has a clean and modern syntax. It has features that allow it to be used across platforms. This means that you can use the same code in Android, iOS, Mac OS X, and Windows. This is a good thing because you don't have to create a different version of your program for each platform. Also, you don't have to learn how to use multiple versions of the same programming language. If you are a programmer, you'll love Kotlin because you can use the same code for all your platforms.

Kotlin and Java are interoperable to 100%. You can call Kotlin from Java and vice versa, which makes the deployment process much easier and less risky. To make it easier to add new features to an existing Android project, you can also use an automatic Java to Kotlin converter that is built into the IDE. This automatic migration from Java to Kotlin is done without affecting the old Java file, as it is only used to create new features in the Kotlin file.
