This is inefficient for object-heavy applications like Minecraft. Prebuilt downloads are rare (legal reasons – Mojang’s

The "Wasm GC" mode in TeaVM allows the generated WebAssembly to define structs and arrays that map to the host environment's managed heap. This means Java objects are represented natively within the browser's memory model, allowing the V8 (Chrome) or SpiderMonkey (Firefox) garbage collector to manage the lifecycle of Minecraft entities, chunk data, and texture maps. In traditional Wasm ports (like those seen in
