This release have a strong focus on fixing bug for JavaScript/TypeScript targets.

It is also trying to make writing cross-target code easier. Thanks to `Compiler.is*` target detection as an alternative to compiler directives.

btw #react here is an alternative to #typescript languge with even stronger type inference and less typing! #fsharp is a #dotnet #ocaml variant, and Fable is a great F# to JS/TS (and more) compiler github.com/jkone27/feli... 🦔🪐

i asked fable what it wants to try after reading turbopack source, and it pitched building an incremental wiki => html compiler (with backlinks and all that), no javascript of any sort. kind of intrigued if it will succeed

My Fable project has been a compiler for HLSL's C-like subset, plus newer SPIRV features. SK's current compiler is glslang+spirv-opt based, and this new one is a 20x smaller binary, compiles 72x faster, compiles shaders 3x faster, and produces equivalent ISA.

Sometimes you just need to roll up your sleeves and look at the compiler source to figure out why something isn't working!

The very old things use a predecessor of Fable and #fsharp compiler services, which may be more work to upgrade
