Runtime Overhead of GC Languages in Wasm
Compiling Go, C#, or Python to Wasm traditionally ships the language's whole runtime — collector, scheduler, reflection — inside the module, inflating size and stealing cycles from your code; C, C++, Rust, and Zig avoid this by managing memory manually. WasmGC moves allocation into the engine's own collector, shrinking modules (Kotlin, Dart, Java) but handing over memory-layout control.
