What Kotlin Is Used For

How To Articles

I’ve recently fallen in love with the Kotlin programming language. It’s a statically typed language that runs on the Java Virtual Machine (JVM) and can also be compiled to JavaScript source code. Kotlin was developed by JetBrains, the same company behind popular IDEs like IntelliJ IDEA and Android Studio. I find Kotlin to be incredibly versatile and easy to use, and I’m excited to share with you what it is used for.

Android Development

One of the main reasons why Kotlin has gained so much popularity is its seamless integration with Android development. In fact, Kotlin is now the preferred language for developing Android applications. With Kotlin, you can write concise and expressive code that is interoperable with existing Java code. This means that you can easily convert your existing Java projects to Kotlin or start new projects from scratch with Kotlin.

Web Development

Although Kotlin is primarily known for its Android development capabilities, it is also a powerful language for web development. Kotlin can be compiled to JavaScript, which opens up a whole new world of possibilities. You can write frontend code in Kotlin and have it run in the browser, leveraging the full power of Kotlin’s language features and libraries.

Server-Side Development

Kotlin is not only suitable for client-side development but also for server-side development. With frameworks like Ktor and Spring Boot, you can build robust and scalable web applications using Kotlin. The concise syntax and the ability to leverage Kotlin’s extensive standard library make server-side development a breeze.

Data Science and Machine Learning

Kotlin is not just limited to building mobile and web applications. It can also be used for data science and machine learning tasks. With libraries like Koma and KotlinDL, you can perform data analysis and build machine learning models using Kotlin. This makes Kotlin a great choice for those who want to explore the world of data science without having to switch to another language.


Kotlin is a versatile programming language that can be used for a wide range of applications, from Android development to web development, server-side development, and even data science. Its seamless integration with existing Java code, as well as its ability to compile to JavaScript, make it a powerful tool for any developer. Whether you’re a beginner or an experienced programmer, I highly recommend giving Kotlin a try. It has truly revolutionized my development workflow and I’m confident it will do the same for you.
