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

Understanding DynamicData in .NET: Reactive Data Management Made Easy
DynamicData is a .NET library that brings the power of reactive programming to collections. It is built upon the principles of Reactive Extensions (Rx), extending these concepts to handle collections like lists and observables more efficiently and flexibly. DynamicData provides a set of tools and extensions that enable developers to manage collections reactively, meaning any changes in the data are automatically and efficiently propagated through the application.

One of the greatest things i discovered recently, is Reactive programming / Reactive Extensions ( https://github.com/dotnet/reactive ).

Patterns for consuming a throttled/rate limited external APIs?
https://github.com/dotnet/reactive has a lot of different time related extensions for "events". Maybe you'll find something for yourself, if you google for rate limiting with reactive.

What is your preferred asynchronous programming library?
Another option is to use the RxJava library in Java. This library uses reactive programming principles to make it easy to write asynchronous and event-driven code. It's particularly well-suited for handling streams of data and allows you to write code that is both efficient and easy to read.
-
MVVM Question: How do you manage the interaction between Model and ViewModel?
I'd use a dedicated event bus based on Reactive Extensions or MediatR to publish domain events from your domain services. This probably doesn't solve all your ViewModel update problems as is, maybe you need to revise the granularity (maybe you can have smaller ViewModels that refresh single property that exposes the Model) and lifespan (sometimes you can create a ViewModel, make it perform it's task and then discard it completely) of your ViewModels.

Async Methods after setting a property.
If you're finding yourself in a situation where you need to turn this behavior into a pattern because there are a lot of View Models that need to execute async business logic in response to some changes, I'd go with something like MediatR or Reactive Extensions. The idea is, again, that some other, probably business-level, component listens to changes in a decoupled way (that means it doesn't subscribe directly to your View Model, but to an event bus instead). View Model publishes change events to the event bus, and business-component reacts to these events by executing the business logic.
