Kotlin is an open-source, general-purpose, statically typed programming language developed by the JetBrains team. It is JVM-based and may be used anywhere Java is currently utilized. It may be used to create Android apps, server-side apps, and a variety of other applications. Kotlin seems to be influenced by other programming languages such as Java, Scala, Python, Groovy, etc. Kotlin gives developers all throughout the world interoperability, code safety, and clarity.


Features of Kotlin


Concise: Kotlin is a functional language based on the JVM. It minimizes the amount of boilerplate code written, making Kotlin more concise.

Easy to learn Language: Kotlin is easy to learn the language, especially for those who have some experience with java. The syntax is easy and somewhat similar to that of java.

Null safety: NullPointerException is one of the most common causes of bugs in the code. Kotlin aimed to eliminate that exception by introducing null safety.

Interoperable: Kotlin easily calls the Java code in a natural way as well as Kotlin code can be used by Java.

Runtime and Performance: It has a fast compilation time and better performance.

Statically-typed language: Kotlin is a statically typed programming language i.e. type of variables is known at the compile time.


Kotlin is a modern programming language first released in 2016. Kotlin was developed for multiplatform applications. Nowadays, Kotlin is widely used for Android development instead of Java as, in 2019, Google announced Kotlin as their preferred language for Android development.
