Kotlin Officially Supports a New Platform: What Does This Mean for Developers?

The JetBrains team has made an important announcement that is already being discussed in the global developer community. The Kotlin programming language, known for its conciseness and safety, has officially expanded its list of supported platforms. Developers can now use Kotlin to create applications for a new target platform, opening up additional opportunities for multiplatform development.

What Has Changed in Kotlin Support?

Previously, Kotlin was available for JVM, Android, iOS, web (via Kotlin/JS), and native applications (Kotlin/Native). With the new update, the WebAssembly (Wasm) platform has been added to this list. WebAssembly support is not just an experiment, but a full-fledged, stable feature ready for use in production projects.

Key aspects of the update:

Full Kotlin Multiplatform support — you can now write shared code for JVM, JS, Native, and Wasm using a single codebase.
High performance — WebAssembly allows Kotlin code to run in the browser at near-native speed, which is especially important for games, graphic editors, and resource-intensive web applications.
Integration with existing tools — Wasm support is built into IntelliJ IDEA, Kotlin Playground, and the Gradle build system. You don't need to install additional plugins.
Compatibility with JavaScript API — Kotlin/Wasm allows calling JavaScript libraries directly, simplifying the migration of existing projects.

Why Is This Important for the Educational Process?

On the PythonLib website, we constantly monitor trends in the programming world. WebAssembly support in Kotlin is not just a technical update, but a paradigm shift. Students and beginner developers can now:

Learn one language for creating applications for any platform — from servers to browsers and mobile devices.
Write high-performance web applications without delving into the complexities of JavaScript.
Experiment with multiplatform projects using a real production-ready tool.

For those studying Kotlin on PythonLib, this means the emergence of new educational materials, code examples, and tasks related to web development with Kotlin/Wasm.

How to Start Using Kotlin/Wasm?

To try the new platform, just follow a few steps:

Install the latest version of Kotlin (2.0 or higher).
In the build.gradle.kts file, add the wasmJs or wasmWasi target depending on your goal.
Configure the settings for your browser or server environment.
Run the build and enjoy the result.

JetBrains has also released detailed documentation and example projects on GitHub to help you quickly get up to speed with the new capabilities.

Conclusion

WebAssembly support is an important step for Kotlin, making the language even more versatile. For the PythonLib community, this is a great reason to pay attention to multiplatform development and expand your toolkit. Stay tuned for updates on the site — we are already preparing a series of articles and lessons on Kotlin/Wasm to help you master the new platform from scratch.
