WasmAssembly

The JVM-to-Web journey continues! In this episode, Thomas Steiner welcomes the original author of Scala.js, Sébastien Doeraene, to discuss the major, experimental leap to WebAssembly. You'll learn why the team decided to target Wasm now and how it complements the existing JavaScript emission. This episode offers a technical deep-dive into how Scala's powerful, nominal type system maps its objects and classes onto Wasm GC, and examines the critical details of interoperability, including what happens when a Scala object crosses the boundary to a JavaScript function. Finally, Sébastien covers the current status of the Wasm ecosystem for Scala.js, and the key limitations you need to know before you flip the `withExperimentalUseWebAssembly(true)` switch. Tune in to discover how a mature typed language is laying a fast, new foundation on the web!

In this episode of WasmAssembly, your host Thomas Steiner is joined by Ömer Ağacan and Martin Kustermann from the Dart team at Google. They explore Dart, the language behind Flutter, and how Dart nearly landed in V8 alongside JavaScript, and why Flutter doubled down on Dart and WebAssembly Garbage Collection (WasmGC). Ömer and Martin then share insights on Dart's performance leap from dart2js to dart2wasm, its potential beyond the browser, and what the WasmGC transition means for developers and the broader ecosystem. Finally, they look at Jaspr, Dart-only web apps, or how different browsers are handling WasmGC. This episode again is packed with sharp technical detail and bold visions for the future of WebAssembly.

In this episode, Thomas Steiner chats with Francis McCabe from Google, who's the champion of the JavaScript Promise Integration and the Stack Switching proposals. They go from talking about synchronous assumptions in code over to discussing the JavaScript Promise Integration (JSPI) proposal and how to use it in practice, its performance implications, and how to use it in practice. After exploring a neat side effect of JSPI, namely lazy loading, the fall into the rabbit hole of comparing JSPI to the upcoming ES module integration of Wasm. Finally, Francis gives an overview of his other early stage Stack Switching proposal.

Speaker: Thomas Steiner

In this episode, Tom interviews Deepti Gandluri, the Chair of the WebAssembly Community Group at the W3C. You will hear about the difference between the W3C WebAssembly Community Group and Working Group, how Wasm is standardized, how Deepti got into WebAssembly, and the challenges the WebAssembly team at Google faces being part of the Chrome team. Deepti also discusses her favorite Wasm features, how the Community Group might react to a browser-specific proposal, how WASI might work given browser security constraints, and new Wasm features she's excited about in the context of AI.

Learn about some early WebAssembly history from one of the co-creators of Wasm, Alon Zakai! Follow along how Alon explains how we came from Native Client to asm.js and then finally to WebAssembly, and explore some interesting historical and present day sidetracks on the way.
