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.

Pipe Operator (|>) For JavaScript
There was also a different proposal that allows objects to be extended: https://github.com/tc39/proposal-bind-operator
Personally, I don't use classes much, but sometimes I think free functions a little bit hard to find, so I tend to experiment with the following pattern.
interface User { … }
const User = {

JavaScript tutorials
In modern JS, you can export each function directly without putting them in an object. It also allows you to call a function with a specific “this” value, function.bind(object)(args). As a matter of fact, there’s a syntax proposal proposal and to do exactly this, object::function(args). This proposal could make what you describe pretty popular.

I don't think you want realms so much as protocols or extensions, the latter assimilating the beloved bind operator.

The Truth about Svelte
I think it is a shame that the Observable proposal [1] still seems somewhat stuck in Stage 1. It's a better idea than just raw event emitters because of composability (if no other reason). Making Observables "first class" could go a long way to unifying a lot of reactivity patterns in various frameworks, in theory at least.
To be fair, Observables and especially Observable composition has a rough learning curve and many frameworks like Svelte intentionally prefer implict reactivity and avoiding things like explicit Observables because they are seen as too complex/"too hard" for the average developer.
(Then you get awful worst of both worlds frameworks like Angular that sort of rely on Observables but yet also don't trust teaching Observables and wind up with code that isn't properly Observable and so also has all the code for implicit reactivity and is full of nasty escape hatches that cause all sorts of composition problems and unnecessary side effects.)

Example of Asynchronous programming using Observer pattern vs Promise
JavaScript doesn't have any built-in observables (addEventListener is part of the DOM API specific to browsers) though there is an old observable proposal collecting dust. I think ReactiveX (RxJS) is pretty much the go-to for any kind of observable functionality you may want. That may be a good place to start to really see what observables can do.

Observablelar streamlarga asoslangan reaktiv dasturlash paradigmasini olib kiradi JSga. Shaxsan menga eng yoqqan takliflardan biri. Bu haqida ham alohida maqola yozish niyat bor. RxJS (Angular) bilan ishlab ko'rganlar bo'lsa buni nimaligini juda yaxshi tushunishadi, endi bu library emas balki native 🚀 !!!

4 Ways to Handle Async Operations in Javascript
Observable is an object that takes a stream of data and emits events over time to react accordingly. There is a talk to add it to the ECMAScript standard and its proposal is here. Till now it is not part of the ECMAScript standard so to use it, you have to use a third-party library and the well-known Reactive Extension in Javascript is RxJs.

Well, the answer is surprisingly no. But, there is an active tc39 proposal going on around for a while, didn’t find it much active though, you could watch out here — https://github.com/tc39/proposal-observable

Why do we need rxjs library as JavaScript is reactive by default?
RxJS is an implementation of observables which do not exist natively in JavaScript. There is a proposal for adding observables to the language, but it's only stage 1 and hasn't been active for years.
