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.

TypeScript Is Surprisingly OK for Compilers
> no pattern matching/switch expressions
They're still waiting on the do expression proposal for that (https://github.com/tc39/proposal-do-expressions), which has been in the bikeshedding stage for the past five years.
-
[AskJS] Opinions on using self executing functions as multi-line expressions.
At some point, it may be superseded by do blocks, but for now it's really your best bet.
-
What is this called? { id ? <Dashboard/> : <Login/> } and can I make it check for multiple things like a switch case?
But there is a proposal for do-expression : https://github.com/tc39/proposal-do-expressions

Using {Blocks} in Rust & Go for Fun & Profit
It's also the reason why do expressions are my most anticipated feature for JS.
-
Pipe Operator (|>) For JavaScript
> They should repurpose `do` so that `do {}` (without the `while`) is an expression that you can put statements inside and return the last statement.
There's a proposal for precisely that. Unfortunately, only Stage 1 though.
https://github.com/tc39/proposal-do-expressions
- Is a single ternary operator inside the returned JSX acceptable?
-
[AskJS] Is there ever a good use for loose blocks in JS?
It's one of the main reasons why I really want the do-expression propsal to work out, because then it would become:
- The TC39 Process
-
[AskJS] What are still present issues in contemporary (2022) JavaScript?
Do blocks. Okay, this is actually a proposal so maybe someday. Basically blocks that can resolve to an expression.

'The best thing we can do today to JavaScript is to retire it,' says JSON creator Douglas Crockford • DEVCLASS
Tomorrow, do expressions:

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.
