What’s Kotlin

How To Articles

Kotlin is a programming language that has gained a lot of popularity in recent years. As a software developer, I have had the opportunity to work with Kotlin on several projects, and I must say, it has quickly become one of my favorite languages to work with.

First of all, let’s talk about what Kotlin is and where it came from. Kotlin was developed by JetBrains, the same company that created popular IDEs like IntelliJ IDEA and PyCharm. It was first released in 2011, but it gained significant traction in 2017 when it was announced as an official language for Android development by Google.

One of the reasons why Kotlin has gained so much popularity is its interoperability with Java. This means that you can easily mix Kotlin and Java code in the same project, which makes it a great choice for teams that are transitioning from Java to Kotlin or have existing Java codebases. The seamless integration between the two languages allows for a gradual migration rather than a complete rewrite.

One of the standout features of Kotlin is its conciseness. Kotlin has a more concise syntax compared to Java, which leads to less boilerplate code. It has features like data classes, smart casts, extension functions, and null safety, which help reduce the amount of code you need to write and improve readability.

Another feature I love about Kotlin is its support for functional programming. It brings powerful concepts like lambdas, higher-order functions, and immutability to the table. This makes it easier to write clean, maintainable, and testable code. Functional programming was something that I always wanted to explore, and Kotlin provided the perfect opportunity for me to do so.

When it comes to Android development, Kotlin shines. It has excellent support for all the Android APIs and frameworks, and it even has some features that are specifically designed for Android development. For example, Kotlin’s null safety helps eliminate null pointer exceptions, which are a common headache in Java development.

Overall, my experience with Kotlin has been fantastic. It is a powerful, expressive, and modern programming language that offers a lot of benefits for developers. Whether you are working on Android apps, backend systems, or any other type of project, Kotlin can be a great choice.


In conclusion, Kotlin is a programming language that has taken the developer community by storm. With its seamless integration with Java, conciseness, support for functional programming, and excellent Android development capabilities, Kotlin offers a lot of advantages. As someone who has had firsthand experience with Kotlin, I can confidently say that it is a language worth exploring and considering for your next project.
