ruby.wasm also enables JavaScript to call Ruby libraries.
summary
ruby.wasm now targets calling Ruby from JavaScript by adding a minimal loader and improving value wrappers: Node.js demo uses jsrequire_local to load doc.rb, eval Doc.new, then invoke methods via call("bow") and read properties with call("count_to_bows") followed by to_string. Current gaps: RbValue only converts String, method calls must use call, and no high-level eval_file yet. Binary sizes are ~31 MB uncompressed (≈8 MB gzipped). Work continues on richer conversions, eval_file, and seamless type mapping.
