Kotlin is a modern statically typed programming language developed by JetBrains, designed to be used across different platforms. WebAssembly, a portable binary format designed to be fast and safe, enables running high-performance code in various environments. Combining the two technologies, Kotlin/Wasm allows developers to write efficient and portable code that can be executed in any Wasm-enabled environment and build from high-performance web applications to serverless functions. This session will be an overview of the latest developments in Kotlin/Wasm: tools, compiler, and the ecosystem around it. Zalim will showcase practical examples, demonstrating how Kotlin/Wasm could be used inside and outside of browsers. Looking ahead, you will see the future prospects of Kotlin & WebAssembly. Come and learn what's new and exciting!
