reflex
Interactive programs without callbacks or side-effects. Functional Reactive Programming (FRP) uses composable events and time-varying values to describe interactive systems as pure functions. Just like other pure functional code, functional reactive code is easier to get right on the first try, maintain, and reuse. (by reflex-frp)
purescript
A strongly-typed language that compiles to JavaScript (by purescript)

The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

On inheritance and why it's good Rust doesn't have it
There's other people around here who would like to know your opinion about these GUI frameworks! I haven't written a GUI in Rust personally, but my favorite GUI framework is not at all OOP: https://reflex-frp.org/

Interactive animations
FRP solutions sound very attractive. But reflex seems to be stuck on the outdated GHCJS, and I haven't been able to get it to build. The newer JS output in GHC doesn't yet have DOM support. And even if I used one of those, figuring out how to interact with a LaTeX renderer might be tricky.

The Quest for the Ultimate GUI Framework
I only have experience using Reflex, which I regard as the main contender for FRP UI libraries in the Haskell sphere. It's got a flashy website, but I think the documentation is a bit disorganized -- it took a long time for me to figure out how to get going with the library (you find some pieces of knowledge scattered here and there, if you look hard enough). My plan was to learn it well enough to onboard other people, but I don't think I could convince anyone who hasn't already decided that they're gonna make UIs in Haskell no matter the required effort.

Simple GHC stack for a novice
Once someone has spent a bunch of time with Haskell and sees the value, they will find Nix if it makes sense. Maybe they'll want to play with https://reflex-frp.org, or they'll discover they want a better way to package 3rd-party dependencies, or they start using NixOS and want to nix all the things, etc. etc. Or, maybe they'll never find a use for it, and that's okay.

Reflex natively supports iOS, along with Android, desktop and web. I would recommend it for functional reactive programming in Haskell: https://reflex-frp.org

HTML5 Ubuntu App with native component?
It's been awhile since I've tried to get into Ubuntu Touch/Linux mobile development in earnest. I'm currently working on an app using the reflex framework that I hope to eventually target Android, iOS, Desktop, and Linux Mobile.

Event driven programming in haskell
If you're talking about the current Elm approach, I'm not sure. Otherwise, the paper I linked to notes some of the FRP libraries that existed at the time, some of which are still supported today (like reactive-banana), and otherwise I'd suggest looking at reflex, mentioned in the first post in this thread. I don't think it existed at the time the Elm paper came out.

Building React Components Using Unions in TypeScript
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.

Why I'm Leaving Elm
PureScript[1][2] seems pretty alive these days. From my relatively small, self-contained experiments, it's a lot more flexible and expressive than Elm at the expense of (maybe?) being a bit harder to learn up-front.
