Its design philosophy is focused on developer productivity, safety, and seamless integration with existing ecosystems. + +- **Full Java Interoperability** + Kotlin is 100% interoperable with Java, allowing teams to adopt it gradually in existing codebases. Developers can use all existing Java libraries, frameworks, and tools without any modification. + +- **Multiplatform Development** + Kotlin supports true multiplatform development, enabling code sharing across Android, iOS, JVM, JavaScript, WebAssembly, and native platforms through Kotlin Multiplatform. This significantly reduces duplication and improves maintainability. + +- **Concise and Readable Syntax** + Kotlin reduces boilerplate code through smart language design, making codebases more compact, readable, and easier to maintain. Common programming patterns are supported natively in the language, resulting in cleaner code. + +- **Strong Type System and Null Safety** + Kotlin’s type system helps eliminate entire classes of bugs, especially null pointer exceptions. Null safety is built into the type system, making your applications more stable and secure. + +- **Tooling and IDE Support** + Developed by JetBrains, Kotlin has first-class support in IntelliJ IDEA and Android Studio. It benefits from deep tooling integration, including code completion, refactoring, debugging, linting, and more. + +- **Modern Language Features** + Kotlin includes powerful features such as extension functions, coroutines for asynchronous programming, sealed classes, data classes, smart casts, and inline functions—providing developers with expressive and flexible language constructs. + +- **Open Source and Backed by JetBrains** + Kotlin is an open-source language governed by the Kotlin Foundation. It’s actively developed and maintained by JetBrains with contributions from a vibrant and growing global community. + +- **Safe and Production-Ready** + Kotlin is battle-tested in production by companies like Google, Pinterest, Netflix, Uber, and Coursera. It is the preferred language for Android app development and is used at scale in backend, web, and cross-platform applications. + +- **Actively Evolving Ecosystem** + The Kotlin ecosystem is growing rapidly, with tools, libraries, and frameworks emerging to support everything from web development (e.g., Ktor, kotlinx.html) to data science, server-side applications, and native development. + + ## Kotlin Multiplatform capabilities Support for multiplatform programming is one of Kotlin’s key benefits.
