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.

ASP.NET Core Blazor
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.

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.
-
F(#)ront-end Experience like Re-Frame (clojure(script))?
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.

Should I pick up OCaml or Haskell?
Try F# with Elmish.

Has TypeScript made you a better developer?
I never tried Elm directly, but I have used the F# equivalent Elmish - super productive idea.
-
F# and WebAssembly
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

Managing State in Comet
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:

Haskellers who moved to Rust: What has been your experience?
You can swap-out implementations for testing, avoid the crazy N^2 instances issues, etc. They're pretty cool. Currently there are many competing libraries. polysemy and eff both have good examples on their homepages.
-
What are the current hot topics in type theory and static analysis?
Effect systems and Algebraic effects. ocaml has just released a stripped-down effect system. People are also working on Effect systems for Haskell (eff, fused-effects, effet). Koka is a language built with effects first and foremost and it’s rapidly gaining popularity. Unison also has effects.

[ANNOUNCE] GHC 9.6.1 is now available
There are also a few subtle issues that arise with delconts related to semantics of higher order effects (see here and here), but they might be solvable.

Effectful | Paweł Szulc | Lambda Days 2022

Looking for languages that combine algebraic effects with parallel execution
You'll get fearless parallel with STM in the mixture, and GHC is getting a work in progress effect system for Haskell, as Delimited continuation primops has been merged.
-
Should I pick up OCaml or Haskell?
My last example is algebraic effects, some of which have been made possible in a both practical and efficient way thanks to extremely recent research, and that I can use to implement architectures like Ports and Adapters or Clean Architecture and have very maintainable code. (Extensible Effects — An Alternative to Monad Transformers was published in 2013, Effect Handlers in Scope was published in 2014 and they are behind Polysemy, while there is ongoing work on effects with even better performance, like Eff)

Opinions on Reader + Continuation-based IO?
Here is link number 1 - Previous text "eff"
-
Where's more discussion of the designs of effect systems?
Languages such as Koka only support algebraic effects, not scoping operations such as catch and listen. The Effect Handlers in Scope paper introduces scoping operations, which lead to the Haskell libraries fused-effects and polysemy, but they turned out to have some weird semantics. eff is her effort to fix that.
-
Languages that don't support Error-Catching as a Control Structure?
There are a few languages that have algebraic effect systems, most notably Haskell, but these systems are implemented as libraries, not baked into the language (which can have advantages and disadvantages).
