W3C Finalizes WebAssembly 3.0 with Native Garbage Collection
The World Wide Web Consortium (W3C) has officially finalized the WebAssembly 3.0 specification, marking the biggest upgrade to web binary execution since its inception. Key additions include native garbage collection primitives, robust multi-threading, and relaxed SIMD extensions for hardware acceleration.
Native Garbage Collection Enables Seamless Managed Language Portability
Prior to WebAssembly 3.0, managed languages like Java, C#, and Go had to bundle their own heavy garbage collection runtimes into compiled binaries, leading to bloated download sizes. With native browser GC integration, WebAssembly applications can directly reference host DOM objects with minimal memory overhead.
