AssemblyScript is a great idea, and has some excellent people working on it. I posted about this earlier, and Aaron Turner replied. His "wasmboy" Gameboy emulator is a perfect example of just what AssemblyScript is good for, and he gave an interesting talk about it too. https://news.ycombinator.com/item?id=20079367 DonHopkins on June 3, 2019 | parent | favorite | on: Compiling C to WebAssembly Without Emscripten Anybody used or have opinions about AssemblyScript? https://github.com/AssemblyScript/assemblyscript >AssemblyScript compiles strictly typed TypeScript (basically JavaScript with types) to WebAssembly using Binaryen.

/torch2424/wasmboy >Gameboy Emulator Library written in Web Assembly using AssemblyScript, Debugger/Shell in Preact Here's an excellent talk about wasmboy by the author, Aaron Turner -- he's done some really outstanding work: https://www.youtube.com/watch?v=ZlL1nduatZQ Since you can compile AssemblyScript into JavaScript with the TypeScript compiler as well as into WebAssembly, you can compare the speed of JavaScript -vs- WebAssembly on the same source code.

And made wasmboy, which uses AssemblyScript: https://github.com/torch2424/wasmBoy But that being said, usually when people are interested in the language, we usually direct them to the "n-body" example: https://github.com/AssemblyScript/assemblyscript/blob/master... . Which kind of looks more typescript-y :) Also, just to stay on topic, I think walt is awesome. Stoked to see so many projects coming up with a "Wasm for JS devs" approach/story. torch2424 on June 3, 2019 [–] Hello! Aaron Turner here, thank you for all the kind words! :) Yes I did all those things, and stoked to see people excited about it! Definitely feel free to reach out anytime about AssemblyScript or WasmBoy. Would love to chat with you / anyone interested. We also have a slack channel you can reach out and get invited to (see the wiki sidebar): https://github.com/AssemblyScript/assemblyscript/wiki Thanks again!
