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.

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

The huge potential of Kotlin/Wasm
Also, js has an ongoing immutable value data types proposal.

How Valtio Proxy State Works (React Part)
Automatic render optimization is to do this automatically. Is this possible? It's possible with utilizing proxies. Proxies allow us to detect state property access. I have been working on this for years, and react-tracked is one of the resulting projects that use this technique. We have an internal library called proxy-compare.

React Tracked: Manage state and prevent excessive re-rendering
While in a smaller application, excessive re-rendering may be unnoticeable or have no negative impact, as your application grows, each re-render may cause delays or lags in your UI. In this tutorial, we’ll use React Tracked, a library for state usage tracking, to optimize our application’s performance by preventing unnecessary re-renders.

What are Tuples and Records in JavaScript?
The best, and perhaps only approach I have found so far is react-tracked. It does some internal tracking with proxies that I don't quite understand, but it actually works as advertised with a very minimal API.
What are some alternatives?
zod - TypeScript-first schema validation with static type inference
use-context-selector - React useContextSelector hook in userland
Immer - Create the next immutable state by mutating the current one
Talkr - Talkr is the lightest i18n provider for React applications. It supports Typescript, provides autocompletion, has 0 dependencies, and is very easy to use.
typescript-eslint - :sparkles: Monorepo for all the tooling which enables ESLint to support TypeScript
rfcs - RFCs for changes to React
typescript-is
todo-app-react - React Application that contains scenario based implementation. It covers nested routing using react-router-dom, state management using react-redux, lazy loading components, suspense api, async call using axios. please refer README.md for more details.
TypeScript - TypeScript is a superset of JavaScript that compiles to clean JavaScript output.
proxy-compare - Compare two objects using accessed properties with Proxy
