    I haven’t tried it yet, so ymmv, but take a look at AssemblyScript. It’s like Typescript with WASM support.

    > And there's been talk of exposing the JS GC to wasm for a few years. Hopefully when that stuff lands, it'll get easier to marshal objects across the gap.

    You don't need a Wasm GC to do this. If you only need js objects to pass on to, say, the host's function or check is null or not, then reference types that are opaque external references: https://github.com/WebAssembly/reference-types/blob/master/p...

    You can even do many more things if you export `Reflect` to WebAssembly: https://github.com/AssemblyScript/assemblyscript/blob/main/t...

    Reference Types are available almost everywhere already (In Safari will be available after 15.0): https://webassembly.org/roadmap

  • An Urgent Notice from AssemblyScript
    news.ycombinator.com | 2021-07-24
  • Integrated a full WebAssembly VM into the engine (potentially as blueprint alt). Here's an example of hot reloading with AssemblyScript. Programming language agnostic scripting.
    WebAssembly lets you use whatever language you want as long as it can compile to WebAssembly. This is using AssemblyScript
  • Is WebAssembly magic performance pixie dust?
    double by factor of 1.5 or 2 or fit to power of two. That's what exactly done in code as you can see: https://github.com/AssemblyScript/assemblyscript/blob/master/std/assembly/array.ts#L16
    If you really think it's noob mistake and you're know how easily to fix that you could try to do that. But first read this comment: https://github.com/AssemblyScript/assemblyscript/issues/1798#issuecomment-819875915

    Instead of JavaScript you have to use something like AssemblyScript and compile the code to wasm inside the browser: https://github.com/AssemblyScript/assemblyscript/tree/master/lib/sdk
