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.

Pipeline Operator great again!
Current Status: You'd have to check the TC39 proposals repository or the official proposal text for the most recent status. As of my last update, it had not yet reached Stage 4 (final stage) of the TC39 process, which means it wasn't part of the ECMAScript specification yet.

Javascript may get it https://github.com/tc39/proposal-pipeline-operator https://youtu.be/dQw4w9WgXcQ

JavaScript Gom Jabbar
It can be further simplified. For example, you don't need two separate functions to extract the first chat completion message etc.
This version:
- uses existing language constructs
- can be immediately understood even by the most junior devs
- is likely to be 1000 times faster
- does not rely on an external dependency that currently has 143 issues and every two weeks releases a new version adding dozens of new methods to things
Note: one thing I do wish Javascript adopted is pipes: https://github.com/tc39/proposal-pipeline-operator

What's new in ES2023?
Still in stage 2 atm https://github.com/tc39/proposal-pipeline-operator
- lizod - spiritual successor of zod less than 1kb
- Updates from the 96th TC39 meeting

Mostly adequate guide to FP (in JavaScript)
Both are active tc39 proposals :)
https://github.com/tc39/proposal-pipeline-operator - Stage 2
https://github.com/tc39/proposal-pattern-matching - Stage 1
Hopefully we get both in the next couple of years.

Tipe - typed pipe
Some time ago I saw how hyped JS community was about pipeline operator proposal. So I tried to make something similar in python. There is how tipe module was created. Check it out if you are interested: https://github.com/mishankov/tipe

CoffeeScript for TypeScript
We often add promising TC39 proposals into Civet so people can experiment without waiting.
We've added https://github.com/tc39/proposal-pipeline-operator, a variant of https://github.com/tc39/proposal-pattern-matching, a variant of https://github.com/tc39/proposal-string-dedent and others.
Since our goal is to be 99% compatible with ES we'll need to accommodate any proposals that become standard and pick up anything TC39 leaves on the table (rest parameters in any position, etc.)

[AskJS] Is JavaScript missing some built-in methods?
The Proposal is for the Hack pipe, so your example would be

Why is nobody talking about how much Proxies break Vue 3?
Private methods: Pretty simple to explain, private methods and fields straight up do not work with ES6 proxies, its a known issue https://github.com/tc39/proposal-class-fields/issues/106

JS private class fields considered harmful
The #x syntax is ugly and many people don't like it. But if you understand how JavaScript works, you'll see that private x is not possible. Some comments on the proposal suggested private #x and there were plenty of other suggestions as well, it may be interesting to read through those discussions.
- Field declarations overwrite properties on the prototype
- Turning “hard private” into “soft private”

All JavaScript and TypeScript features of the last 3 years explained
> - # private... not sure why they didn't just use the "private" keyword, but I don't care. I almost always use TypeScript anyways
One of the reasons was to allow private and public fields of the same name, so that subclasses are free to add own public fields without accidentally discovering private fields. There were many more considerations that went into the design: https://github.com/tc39/proposal-class-fields/blob/main/PRIV....
There was a heated debate about this and the choice of the # sigil back in 2015 at the time private fields were being designed: https://github.com/tc39/proposal-private-fields/issues/14.

Create Ref using React.createRef without using constructor in React?
class App extends React.Component { constructor(props) { super(props); this.state = { counter: 0 }; }} but due to Babel's class-field support, I don't use it anymore

Correct use of arrow functions in React
I am using ReactJS with Babel and Webpack and using ES6 as well as the proposed class fields for arrow functions. I understand that arrow functions make things more efficient by not recreating the functions each render similar to how binding in the constructor works. However, I am not 100% sure if I am using them correctly. The following is a simplified section of my code in three different files.

React component design patterns for 2022
Working with constructor and calling super() before we can set state. Although this has been solved with the introduction of class fields in JavaScript, Hooks still provide a simpler API
