Java has support for functional programming but it’s only available in Java 8, whereas most Android development is done with Java 6 and 7. To help manage the quality of your code, Kotlin makes use of type inferencing, eliminating much of the frustrating and overly tedious syntax that Java developers face. Often, code written in Kotlin is more concise, but it also happens to be a little more complex for those used to programming in Java. Currently, it’s most prominent for Android application development. However, its usage for developing server-side applications for the JVM is increasing.

A data class is a class that does not perform any operation and only contains a state. The advantage of this class is that it provides self-generated code and avoids the implementation of methods within the class. By including the “data” keyword in the class definition, you can avoid setting up everything manually. The compiler takes on the task and generates all necessary getters and setters automatically. You can perform the same tasks and implement the same features with the help of Kotlin and Java.

However, the virtual machine doesn’t support all environments, including embedded systems and browsers. That’s why to run an application in the browser, we need to use JavaScript. Developers no longer need to use Java, an established language, but with a lot of issues.

In one part, due to Google officially supporting it for Android development, and, secondly, because Android is still stuck on Java 6. Kotlin, with its modern features, spread rapidly among the Android developers’ community. Today, Java is really popular for backend development and Kotlin can be used for any kind of server development. Whether it is web apps that serve HTML content, a backend for REST APIs or Microservices, Kotlin can do the job. Not only that, thanks to the Kotlin JavaScript compiler, it can also be used for building frontend web Apps. So it is entirely possible to create a web App using only one language.
