Should JavaScript be split into two languages? Google proposal divides opinion

• Uno Platform

  145 9,078 10.0 C#

  Open-source platform for building cross-platform native Mobile, Web, Desktop and Embedded apps quickly. Create rich, C#/XAML, single-codebase apps from any IDE. Hot Reload included! 90m+ NuGet Downloads!!

  

  > And even if it were accomplished in a central open source library like Flutter, that adds a considerable amount to the package size of any application.

  The download really isn't much different to a typical website. That Flutter demo in wasm is 2 megabytes.

  Avalonia UI's WebAssembly uses canvas in C#: https://avaloniaui.net/

  Uno Platform's WebAssembly implementation uses the DOM rather than drawing to canvas: https://platform.uno/

  Uno's philosophy is to use platform native controls. The benefit is that you get platform native characteristics, the cost is it will never be exactly the same in each browser and platform.

• .NET Runtime

  668 15,476 10.0 C#

  .NET is a cross-platform runtime for cloud, mobile, desktop, and IoT apps.

  

  Garbage collection is solved to the extent that host garbage collection is now available via WasmGC:

  https://v8.dev/blog/wasm-gc-porting

  But languages like C# want more features in WasmGC:

  No direct DOM access yet. You still have to use JavaScript glue code to get at the DOM.

• Flutter

  1,240 166,743 10.0 Dart

  Flutter makes it easy and fast to build beautiful apps for mobile and beyond

  

  > I'd rather we just move to native cross platform applications and stop using a document browser to build interactive applications

  Here you go. Do both native and wasm:

  Binary AST proposal for ECMAScript

  

  Actually I don't want DOM access and GC for wasm. At least not yet. It overcomplicates a lot and I simply cannot imagine that a GC can be one-size-fits-all languages.

  I want fixed-size buffer-backed structs for JS. Basically a DataView as a C struct. This would massively benefit interop and solve some shortcomings of DataView.

  There was a proposal for a binary AST for JS several years ago [1]. Why not just use that as JS0? It's separate and can offer new possibilities as well.
