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.

Erlang: The coding language that finance forgot
I will put in a good word for PureScript for the beam with `purerl`. It's my go-to for writing BEAM code nowadays. Notably PureScript tooling including LSP, package management, etc., just works, so you are able to just get to work in internalizing the way OTP and other Erlangy things are expressed in a statically typed, pure language.
https://github.com/purerl/purerl & https://purerl-cookbook.readthedocs.io/ for more information. Join the PureScript discord and the #purerl channel if you want help.

purerl - Integrating PureScript into Elixir projects
purerl is a compiler for turning PureScript code into Erlang code, so that you're able to write BEAM (the Erlang virtual machine) applications using it.

Phoenix 1.7 is View-less
You've been able to write PureScript that compiles to Erlang and has perfect interop for years, via `purerl`[0]. Using it with Elixir is as simple as adding `purerlex` as a compiler and having your PureScript code automatically compile when `mix` compiles things, and off you go.
In terms of the typing itself, it's exactly what you get in all of PureScript, strict static typing with no `any` or the like. Using `Pinto`, the de facto OTP layer in PureScript your processes are typed, i.e. their `info` messages & state are typed, which means that they are all much more like strongly typed state machines than anything else.
You can see an example of a basic `gen_server` here:
https://pastebin.com/UTEfz7Wg
The differences aren't very big in terms of what you'd expect to be doing. One small thing to note is that the `GenServer.call` expects a closure to be passed instead of having the split between `gen_server:call` & `handle_call`, removing the need for synchronizing two places for your messages being sent and handled.

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.
