Panel Discussion: Browsers & Wasm
Panelat WasmCon 2023 · on Thursday, 2023-09-07· at 13:30· Grand Ballroom I, Hyatt Regency Bellevue, 900 Bellevue Way NE·
summary
Browsers report concrete work: baseline compilers like liftoff and Mozilla’s BBQ compile quickly while OMG/TurboFan and Balder optimize later, and V8 runs a promise-integration prototype for stack switching behind a flag. Engines run a WasmGC origin trial enabling Java/Kotlin-style GC'd languages to compile to Wasm, while threads remains separate today and SIMD, memory64 and multi-memory advance toward shipping. Real apps exist: Ruffle Flash emulation, Unity and Photoshop ports show performance and load-time tradeoffs and cross‑engine tests drive phase‑by‑phase standardization.
