corert VS elmish

An explanation of the problem: https://github.com/dotnet/corert/blob/master/Documentation/u...

Memory was not really designed for having lots of instances of it and doing intensive computations/searches on the instances. The reason for it is that Memory.Span property is actually quite expensive to call. Memory is a union type for storing strings, arrays, and even handles to native memory. Every time you construct it , slice it, or retrieve it's span, lost of machinery related to this union has to run. For example see the source for the Memory.Span property: https://github.com/dotnet/corert/blob/master/src/System.Private.CoreLib/shared/System/Memory.cs#L285.

Yeah I know it's slower on its own, but I was sure it was handled as a faster intrinsic by the runtime. Went to double check and realized I was actually mixing things up with what CoreRT did (see here) but I guess it doesn't apply to CoreCLR. Would be surprised if there weren't any specific optimizations for this with .NET 6+ though, or at the very least with NativeAOT (given they've been porting some bits over from CoreRT and .NET Native too). Will need to go gather more info on this, as it's pretty interesting 🙂

> AOT compilation? I'll believe it when they'll release it, until then, it's all speculation

Devil's in the details, but there -is- AOT compilation[0]. While it hasn't been released as an official product, it has been used for a few projects including a commercial game [1]. And yes, they're looking into the next steps to make it a 'released' thing.[2]

That is a well known issue, also what prevented F# to be properly used in .NET Native.

For those interested in .NET languages with alternative compilation targets, Elmish (https://elmish.github.io/elmish/) is pretty unique.

We use F# on the front end (instead of TS), and thanks to the Fable compiler (which transpiles F# to JS, Python, Dart, PHP and Rust), most of the benefits of an Elm-style model in the UI can be ported to all sorts of different outputs languages. The rust target is in beta, but its promising because the WASM bundle size stands to be dramatically lower.

While the default is reactivity library for Elmish is React, you can swap in Avalonia/FuncUI (https://github.com/fsprojects/Avalonia.FuncUI) pretty easily as well.

Naturally I’d recommend using a better language such as ReScript or Elm or PureScript or F#‘s Fable + Elmish, but “React” is the king right now and people perceive TypeScript as “less risky” for jobs/hiring, so here we are.

Since you're familiar with React + Reframe, you can try Elmish! You can use F# to write [Elmish](https://elmish.github.io/elmish/) apps. It takes the Elm approach to building apps.

Try F# with Elmish.

I never tried Elm directly, but I have used the F# equivalent Elmish - super productive idea.

You can also get nested templates, bind inputs, and radios for example by the way don't be scared by the mutable keyword right there is just to show a brief example in a normal situation you would likely be using Elmish

Comet promotes a variation of the Model-View-Update pattern popularized by The Elm Architecture, Elmish, Fabulous and others. The major parts of MVU are:
