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 = {

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.

[AskJS] Sensible Prototype Extensions?
I don't think you want realms so much as protocols or extensions, the latter assimilating the beloved bind operator.

TC39: Add Object.groupBy and Map.groupBy
Global iterator type is coming: https://github.com/tc39/proposal-iterator-helpers
But a method named `groupBy` on iterators traditionally means a different thing: https://github.com/tc39/proposal-array-grouping/issues/51#is...
Global iterable type it's too late for, since there's many extant iterables in the language and on the web which don't have it in their prototype chain and can't reasonably be changed.

Lodash just declared issue bankruptcy and closed every issue and open PR
Very much agreed. The amount of mileage we get from using Spread (literally the ...) alone has been amazing. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe... Iteration helpers is shipping soon, that'll be a huge help (async iteration helpers will be delayed for a while). https://github.com/tc39/proposal-iterator-helpers .
In the olden days, I feel like the codebases I worked on needed to use .apply() multiple times a week, to figure out some creative way of invoking functions. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe... That's all gone now; I'd take even odds that 50% of my team knows .call and .apply.
Chrome 117 is shipping Object.groupBy() and that's gonna be a huge help in eliminating a lot of the last places we end up using lodash. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe...

Sets and Maps are sorted (by insertion order)

[AskJS] Is JavaScript missing some built-in methods?
Not Generators, but Iterators have a Stage 3 proposal with helpers like these.

Just fighting URLSearchParams and wonder if anyone uses iterators IRL and what I do miss
I guess you are not the only one dealing with this. That’s why there is this proposal https://github.com/tc39/proposal-iterator-helpers So hopefully it will get easier soon. But in most cases you can simply wrap it in Array.from or you can also clone with the spread operator.

Iterator/Generator Exercises?
Let's assume Number.range(), iterator helpers and some isPrime() function. From that we could easily create the following:
