TypeTags .WebAssembly
Overview
WebAssembly is a new type of code that can be run in modern web browsers — it is a low-level assembly-like language with a compact binary format that runs with near-native performance and provides languages such as C/C++, C# and Rust with a compilation target so that they can run on the web.
WebAssembly is designed to complement and run alongside JavaScript — using the WebAssembly JavaScript APIs, you can load WebAssembly modules into a JavaScript app and share functionality between the two.
Usage
import { TypeTags } from 'typetags'
let importObject = { imports: { imported: (arg) => console.log(arg) } }
let res = WebAssembly.instantiateStreaming( fetch('simple.wasm'), importObject).then((obj) => obj.instance.exports.exported())
let maybeWasm = TypeTags.get(res)
console.log(maybeWasm)// → [object Promise]
maybeWasm === TypeTags.WebAssembly// → false
console.log(TypeTags.WebAssembly)// → [object WebAssembly]Metadata (TType)
