TurboScript
Super charged typed JavaScript dialect for parallel programming which compiles to WebAssembly
⚠️ Major re-architecting is undergoing.
New spec (WIP) : TurboScript Spec
Things going to change
-
Binaryen as WebAssembly Backend
-
Interop with TypeScript/JavaScript (Import well typed TypeScript to TurboScript, will not compile to WASM)
-
Import any compiled WASM module to TurboScript
-
Integration with WebPack

TurboScript is an experimental programming language for parallel programming for web which compiles to JavaScript (asm.js) and WebAssembly (targeting post-MVP). The syntax is similar to TypeScript (Hardly trying to fill the gaps) and the compiler is open source and written in TypeScript. TurboScript has zero dependencies.
This is still an experiment and isn't intended for real use yet but we are working towards an MVP release. Please feel free to open issues if it stop working or need a new feature.
