Kotlin
What is Kotlin?
Kotlin is a statically typed programming language developed by JetBrains, aimed at modern multiplatform development. It is designed to interoperate fully with Java, allowing developers to use both languages within the same project.Kotlin runs on the Java Virtual Machine (JVM), and can also be compiled to JavaScript and native code (through Kotlin/Native) for building applications on various platforms.
Some of the key features of Kotlin include:
- Concise syntax: Reduces boilerplate code significantly compared to Java.
- Null safety: Helps eliminate NullPointerExceptions by providing nullable and non-nullable types.
- Extension functions: Allows developers to extend existing classes with new functions without modifying their source code.
- Coroutines: Supports asynchronous programming and simplifies handling long-running tasks.
- Multiplatform capabilities: Enables sharing code between different platforms (iOS, Android, web, etc.).
Kotlin has gained popularity among Android developers since Google announced official support for it as a first-class language for Android app development. Its friendly and approachable syntax, combined with powerful features, makes it a desirable choice for many developers.

- Snippet from Wikipedia: Kotlin
Kotlin () is a cross-platform, statically typed, general-purpose high-level programming language with type inference. Kotlin is designed to interoperate fully with Java, and the Java virtual machine (JVM) version of Kotlin's standard library depends on the Java Class Library. Type inference allows for more concise syntax than Java, while null-safety features reduce a common class of runtime errors. Kotlin mainly targets the JVM, but also compiles to JavaScript (e.g., for frontend web applications using React) or native code via LLVM (e.g., for native iOS apps sharing business logic with Android apps). JetBrains bears language development costs, while the Kotlin Foundation protects the Kotlin trademark.
On 7 May 2019, Google announced Kotlin had become its preferred language for Android app developers. As of 2024, over 95% of the top 1,000 Android apps on Google Play contain Kotlin code. In May 2024, JetBrains released Kotlin 2.0 featuring the new K2 compiler—a complete rewrite offering up to twice the compilation speed of its predecessor—as well as stabilised support for Kotlin Multiplatform. That same month, Google formally endorsed Kotlin Multiplatform at Google I/O 2024, recommending it as the approach for sharing business logic across Android, iOS, and other platforms.

Kotlin is a statically typed programming language for modern multiplatform applications. 100% interoperable with Java and Android, it now supports JavaScript and native with LLVM (including iOS). It was developed by JetBrains in 2011, and designed to be a new language for the Java Virtual Machine (JVM) that can compile quickly.
