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.

Turboprop: JS Arrays as Property Accessors!?!
There is proposal for stdlib, but it will take some time until (if ever) it will reach stage 4.

Don't make me think, or why I switched to Rails from JavaScript SPAs
The working group most in charge of JS is ECMA's TC-39 (TC => Technical Committee) [0]. They've been taking a very deliberate, slow path to expanding the "standard" library because they take a very serious view of backwards compatibility on the web. Some proposals were shifted because of conflicts with ancient versions of things like MooTools still out in the wild, for instance. (This was the so-called "Smooshgate" incident [1].)
This may speed up a bit if the Built-In Modules proposal [2] passes, which would add a deliberate `import` URL for standard modules which would give a cleaner expansion point for new standard libraries over adding more global variables or further expanding the base prototypes (Object.prototype, Array.prototype, etc) in ways that increasingly likely have backwards compatibility issues.
TC-39 works all of their proposals in the open on Github [3] and it can be a fascinating process to watch if you are interested in the language's future direction.

What NPM Should Do Today to Stop a New Colors Attack Tomorrow
There is a TC39 proposal for a "Javascript Standard Library." It's at stage 1, which is better than stage 0.

[AskJS] What is the thing you hate the most about JS?
The standard library is a tough one. There is a proposal for built-in modules but it is very early days and miles away from what is needed. Clojure ships with functions that make the likes of Lodash and Ramda redundant. I think for a dynamic language an extensive library of functions for manipulating collections is essential. It is a real thing that once dynamic language codebases grow too big, they become a challenge to maintain. Therefore having functions that do a lot of common tasks for you mitigates that issue. Paired with immutability, lots of code just becomes data passing through pipelines, giving less surface area for bugs and making everything more concise and declarative.

Union, intersection, difference, and more are coming to JavaScript Sets
relevant issue, which is at the crux of this problem: https://github.com/tc39/proposal-record-tuple/issues/387

The Everything NPM Package
There are still so many basic things that aren't in the JS stdlib, though. A good example is Map - if you need to use a tuple of two values as a key, you're SOL because there's no way to customize key comparisons. Hopefully we'll get https://tc39.es/proposal-record-tuple/ eventually, but meanwhile languages ranging from C++ to Java to Python have had some sensible way to do this for over 20 years now.

Deep Cloning Objects in JavaScript, the Modern Way
If you’re reaching for structuredClone, what you really want is native immutable Record and Tuple syntax, and the companion “deep path properties” syntax which allows for efficient and ergonomic immutable updates:

Cool language features that Rust is missing?
It will be called "record" in JavaScript which will swing the popularity back the other way I guess (currently a language proposal)
-
Why doesn't TypeScript properly type Object.keys?
I suspect considering the strong desire to maintain consistency with JavaScript, we will eventually see something that when the Record proposal passes through tc39

ES2023 features list!
I hope the Record and Tuple proposal makes it through
-
ES2023 introduces new array copying methods to JavaScript
I mean, I'd love some real immutable/persistent data structures in JS by default, or even some Immer-like syntax sugar. Something like the record/tuple proposal would be awesome.

What's new in ECMAScript 2023
This will become very useful once Records and Tuples are a thing, because it allows you to store object references in a record/tuple (which by definition can only contain primitives).

[AskJS] Is JavaScript missing some built-in methods?
Record and tuple is at stage 2
