VisualFSharp VS F#

If you're interested, you could further raise this on F# discord server or in https://github.com/dotnet/fsharp, F# is effectively a community-managed language so if there's a particular change you'd like to see, there is a high chance you can just make it happen if you have time to see it through.

Thanks for the tips! I had thought there were still some other gotchas with AOT and F# but it looks like the list is smaller than last time I looked. https://github.com/dotnet/fsharp/issues/13398

Nullness checking

Not quite accurate with the Parallel example. Don Syme is explicit that applicative `async` should not implicitly start work in the thread pool (https://github.com/dotnet/fsharp/issues/10301#issuecomment-7...).

There's docs about how the compiler generally does optimizations here: https://github.com/dotnet/fsharp/blob/main/docs/optimizations.md

You should add your +1 to https://github.com/dotnet/fsharp/issues/8764, which would add a syntax like #r: project ... to FSI.

So when people are mad about MS and F#, one can see here that: https://github.com/dotnet/fsharp/graphs/contributors MS does a lot more for F# then people being all pessimistic in reddit.

This year I've been attempting Advent of Code in my favourite programming language, F#. This is a beginner(ish) centered post about making incremental changes from the smallest possible solution to something more robust.

I can recommend polyglot notebooks in vs code, so you can mix different languages.Take a look athttps://fsharp.org/ for some project ideas and frameworks.

I have many less followers on Mastodon than in the Birdsite (40 vs 341), yet my activity has generated many more interactions than there. Not only that, among the users who decided to interact with me I counted: a co-discoverer of the Laniakea supercluster, one of the lead developers behind F#, the author of many important books on Java & JVM, plus many others. I'm literally a nobody, but this time there was no algorithm relying on relevance and engament metrics to decide what to present to each one of us.

FP devs differ based on language here. Elm, like F#, tends to encourage "a bunch of functions and types in a file". While Elm supports modules, we don't really care where it came from; they're all pure, all deterministic, the compiler tells us if it works.

The builtin fsharp collections actually are just "immutable", not persistent as you mention. (Ref: https://github.com/fsharp/fsharp/blob/master/src/fsharp/FSharp.Core/map.fs. This is just an AVL tree that returns a copy on mutations: https://github.com/fsharp/fsharp/blob/577d06b9ec7192a6adafefd09ade0ed10b13897d/src/fsharp/FSharp.Core/map.fs#L118)

You can dive into .NET ecosystem by trying F#. It's functional-first language so this should be familiar.

ReScript code is just like F# or OCAML; it doesn’t have a function parse phase like JavaScript, so we have to define our functions and types first before we can use them. That’s fine, but makes explaining the code backwards (meaning you start at the bottom of the file and work your way up), so we’ll start at our lambda handler and explain each part, regardless of where it’s defined.

F# is a JavaScript and .NET language for web, cloud, data-science, apps and more.

Also a programming joke
