A TypeScript-like language for WebAssembly.

Project mention: Do any engines or optimizers product TS-specific performance gains? | reddit.com/r/typescript | 2023-03-24

If you can guarantee that Typescript type hints will always be followed, you can turn it into more optimised code. Unfortunately, this means you've got to break Javascript semantics, so this means creating a new language, but people have done it. For example, AssemblyScript is a language that is designed as a strict subset of Typescript that compiles directly down to WebAssembly instead of Javascript, producing much more efficient code (most of the time). The tradeoff is that it has some slightly different semantics to Javascript, which means your existing codebase — and most of the libraries you use — will probably require some adaption before running correctly in AssemblyScript.

Small but complete dynamic Forth Interpreter/Compiler for and in WebAssembly

Project mention: Bunch of questions about forth | reddit.com/r/Forth | 2023-02-23

Concerning the point 8. There is an online Forth system demo Thurtle (in the browser) with turtle graphics, which is based on WAForth.

Research WebAssembly Engine

Project mention: Wasmtime 1.0 | news.ycombinator.com | 2022-09-20

Congrats to the Wasmtime team on the 1.0 release!
I'm happy to see that more runtimes are maturing and getting use on production cases... I can't wait to see and show what the future entails for WebAssembly on both the server side and the browser!
Keep up the good work. Also I'd like to use this message to congratulate other runtimes that I'm excited about (apart from Wasmer, of course!): Wizard Engine [1], Wazero [2] and Lunatic [3].
The future is bright in Wasm land :)

wasm2lua: converting WASM into Lua

Project mention: [ComputerCraft] Is it possible to run Doom on CC? | reddit.com/r/feedthebeast | 2022-05-15

You could try converting WASM to Lua using something like wasm2lua but a lot of work would still be required to get the display/sound/input working inside CC.
