Features & Specs

  1. Functional Programming Paradigm

    F# primarily supports functional programming, which promotes immutability and first-class functions, leading to more predictable and maintainable code.

  2. Interoperability

    F# provides seamless interoperability with .NET libraries and languages like C#, allowing developers to leverage a vast ecosystem of tools and libraries.

  3. Conciseness

    F# code tends to be concise and expressive, reducing boilerplate code and enhancing readability.

  4. Type Inference

    Powerful type inference capabilities reduce the need for explicit type annotations, making the code easier to write and refactor.

  5. Asynchronous Programming

    F# provides robust support for asynchronous programming, enabling the creation of responsive applications and efficient I/O handling.

  6. Community and Resources

    An active community and wealth of online resources provide support and facilitate learning through forums, tutorials, and documentation.

  7. Multi-Paradigm

    Despite its functional core, F# also supports imperative and object-oriented programming, offering flexibility to developers.

Social recommendations and mentions

We have tracked the following product recommendations or mentions on various public social media platforms and blogs. They can help you see what people think about F# and what they use it for.
  • Solving the NY Times "Pips" game with F#
    We'll use F# to implement this algorithm because functional programming is a good choice for "black box" problems like this that have no side-effects, and .NET is an easy, fast platform to work with. (F# is actually a great all-purpose language for just about anything, but I digress.). - Source: dev.to / 9 months ago
  • What's New in F# 9
    It's an open-source project with its own F# Software Foundation. If Microsoft drops it, I think it would continue. https://fsharp.org/. - Source: Hacker News / over 1 year ago
  • Rust panics under the hood, and implementing them in .NET
    Before Rich made Clojure for the JVM, he wrote dotLisp[1] for the CLR. Not long after Clojure was JVM hosted, it was also CLR hosted[2]. One of my first experiences with ML was F#[3], a ML variant that targets the CLR. These all predate the MIT licensed .net, but prior to that there was mono, which was also MIT licensed. 1: https://dotlisp.sourceforge.net/dotlisp.htm 2: https://github.com/clojure/clojure-clr. - Source: Hacker News / almost 2 years ago
  • Roc โ€“ A fast, friendly, functional language
    Oh yeah. A key hindrance of F# is that MS treats it like a side project even though it's probably their secret weapon, and a lot of the adopters are dotnet coders who already know the basics so the on-boarding is less than ideal. https://fsharp.org/ is the best place to actually start. https://fsharpforfunandprofit.com/ is the standard recommendation from there but there's finally some good youtube and other... - Source: Hacker News / over 2 years ago
  • Building React Components Using Unions in TypeScript
    Naturally Iโ€™d recommend using a better language such as ReScript or Elm or PureScript or F#โ€˜s Fable + Elmish, but โ€œReactโ€ is the king right now and people perceive TypeScript as โ€œless riskyโ€ for jobs/hiring, so here we are. - Source: dev.to / almost 3 years ago
  • I am a ChatGPT bot - Ask me anything #2
    Are you really a bot? Yes, I'm a small F# program that glues together the public API's provided by Reddit and OpenAI. I was created by /u/brianberns. You can find my source code here. Source: over 3 years ago
  • I am a ChatGPT bot
    The bot is written in F#, which is a .NET language (like C#). Source: over 3 years ago
  • From Script to Scaffold in F#
    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. - Source: dev.to / over 3 years ago
  • for newbie , VScode+ionide or VisualStudio
    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. Source: over 3 years ago
  • The comeback of the Fediverse and the Old Web
    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... - Source: dev.to / over 3 years ago
  • Chicago and London TDD Styles for Functional Programming
    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. - Source: dev.to / almost 4 years ago
  • Coming from Scala
    You can dive into .NET ecosystem by trying F#. It's functional-first language so this should be familiar. Source: about 4 years ago
  • Parsing Lambda Error Logs in ReScript & Python
    ReScript code is just like F# or OCAML; it doesnโ€™t have a function parse phase like JavaScript, so we have to define our functions and types first before we can use them. Thatโ€™s fine, but makes explaining the code backwards (meaning you start at the bottom of the file and work your way up), so weโ€™ll start at our lambda handler and explain each part, regardless of where itโ€™s defined. - Source: dev.to / about 4 years ago
  • Please put units in names
    F# is a JavaScript and .NET language for web, cloud, data-science, apps and more. Source: over 4 years ago
  • TypeScript vs. ReScript vs. F# - a simple comparison of syntax
    Let's compare how 3 languages that compile to JavaScript - TypeScript, ReScript and F# with the Fable compiler - are able to chain immutable data. - Source: dev.to / over 4 years ago
  • Have you tried functional programming?
    Some of the most popular programming languages include Haskell, Clojure, Scala, Erlang, F#, Rust, etc. - Source: dev.to / about 5 years ago
  • Few newbie question from C# coder
    9) Check out the links under "Contribute" here: https://fsharp.org/. Source: almost 5 years ago
  • What's a nerd debate that will never end?
    That's what I thought until I stumbled upon F# where whitespace indenting is optional; you can use either semicolons or new lines. Source: about 5 years ago
  • GDScript progress report: Feature-complete for 4.0
    If you're interested, check out Cornell's course/book, Functional Programming in OCaml. It's an excellent resource for learning FP, using a language called OCaml that's pretty easy to learn and read. (And also just a nice language in general.) You can even sort of indirectly translate the OCaml knowledge to Godot, too, because you can piggyback off Godot's C# support to use F#, a language that's loosely related... Source: about 5 years ago
