About Kotlin
Kotlin is a concise, multiplatform programming language that runs on the Java Virtual Machine and compiles to various targets. Developers use it to build backend, mobile, web, and desktop applications. The language emphasizes simple, asynchronous, and functional programming patterns, with null safety built into its syntax to help prevent common errors. Kotlin integrates with existing JVM ecosystems and supports interoperability with Java code.
Kotlin is developed by JetBrains and distributed under the Apache Software License 2.0. The language can be used freely for open-source and commercial projects. Development tools and plugins are available for major IDEs, and the language includes support for multiplatform code sharing, allowing developers to write shared logic that runs across different platforms and targets, including WebAssembly.
