This document describes how to execute WASM module on Node.js.
This document describes how to execute WASM module on v8, including on node.js and on chrome.

> Note: Wasmnizer-ts follows the latest WasmGC spec, which requires `V8 v11.9+`, but the latest nodejs (v21.5.0) is using `V8 11.8.172.17`, so currently the generated WASM module can't execute on any nodejs releases.

> If you do want to try on nodejs, you can reset to commit `94cf9929421d47a9976fa6edf74b25ef2a00ee12` to build the compiler, which is compatible to older V8 versions.

- Experimental WebAssembly
- WebAssembly Garbage Collection
- WebAssembly Stringref

### How to Run
Start a server, open the `run_module_on_chrome.html` on chrome, fill in with the wasm path, the wasm function name, and arguments(must be separated by commas), then click `submit` button, and the result will be print on the page.
