Converting 40K lines of TypeScript.

⚠️ Experimental. Do not use this. ⚠️

Stripped back to only remove TypeScript types, (and compile TypeScript enums into objects).

No support for classes, module transforms, JSX, Flow.

Requires a WASI compliant WebAssembly runner to execute.

cat './input.ts' | wasmtime ./build/out.wasm > './output.js'

Node.js has (currently experimental) support. https://nodejs.org/api/wasi.html

cat './input.ts' | node --experimental-wasi-unstable-preview1 ./bench/node-wasi.js > './output.js'
