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.

Show HN: Scientific Calculator for iOS
I've just released an update for the iOS version of my app, TechniCalc.
It's a scientific calculator aiming to provide a comprehensive math feature set while not compromising on the user interface. I found too many apps had a great story for one half of that, but fell short on the other.
The app itself is React Native. The calculation and editor logic are in ReScript, and this part is open source too! (if you're interested - https://github.com/jacobp100/technicalc-core)
I'd love to hear all your feedback!

What is your “I don't care if this succeeds” project?
I’m working on a scientific calculator app - TechniCalc
https://jacobdoescode.com/technicalc
It’s done in react native and a good amount of it is also open source.

Can you make your own JavaScript by implementing ECMAScript standard?
You also wouldn't really be creating your own new programing language. You would be creating something that can run JavaScript by following JavaScript standards and syntax. You might be able to add some non-standard features of your own on top of those standards, or include your own standard library of helpers or utilities, but you can't completely make a new or alternative language and then load it in the browser (or at least not by reimplementing ECMAScript standards... you actually can make your own language that runs within any Javascript enviroment, if you provide an interpreter or compiler that transforms it into valid JS. Some people have done something like this, eg Elm: https://elm-lang.org/).

What is the best way to present the user the results of Haskell computations?
You should at least have a look at https://elm-lang.org/ it is a pure functional language like Haskell (although with fewer fancy syntax/type classes) but it has some lovely libraries for visualisation and even with plain elm (+ elm-ui) doing string transformations can be easily done.

Building React Components Using Unions in TypeScript
I get it. However, the whole point of using Unions to narrow your types, ensure only a set of possible scenarios can occur, and only access data of a particular union when it’s safe to do so. That’s some of what pattern matching can provide, and 100% of what using switch statements in TypeScript with their Discriminated Unions can provide. Yes, it’s not 100% exhaustive, but TypeScript is not soundly typed, and even Elm which is still has the same issue TypeScript does: You’re running in JavaScript where anything is possible. So it’s good enough to build with and much better than what you had.

How to render a basic calendar UI in Elm
The beauty of a language like Elm (and other lambda-calculus / functional programming inspired languages) is that there's very little transformation involved in going from an idea to code. And that seems to have a big impact on getting things done.

Is it possible to write games like Pac-Man in a functional language?
I think the most fun and approachable way for beginners to build games with functional programming is with Elm [1].
See a few (small, demo) games built by the community in [2] .
Notice Elm has abandoned the FRP approach in favor of Model-View-Update [3].

haskelm - Haskell to Elm translation using Template Haskell. Contains both a library and executable.

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.
