" summary

Describes a Scala-to-WebAssembly compiler that leverages WebAssembly Garbage Collection (WasmGC) and the WebAssembly Component Model to support high-level-language features and interoperability. Reports an implementation and performance evaluation comparing the generated Wasm against JavaScript- and JVM-targeting compilers (up to 3.4× faster than the JS target, up to 3.5× slower than the JVM target) and measures foreign function call overhead—showing calls are >4× slower than Rust-to-Wasm due to memory copies.
