This is why #Rust is not only about memory safety/performance, but about correctness 👇
Did you know that in #JavaScript when `fetch`ing the same Request/Response twice will error (when containing a body)!?
It is because bodies are Streams, which can only be read once! You can clone the Request/Response/Body, but this comes with its own caveats (in the worst case the clone will buffer the body fully in memory!).
#RustLang solves this by borrow checking and good API design...

@wojtek or just the baddies giving JavaScript a bad name :P
@konstantin yes, yes… #JS is always innocent… it's always everyone else… Shai-Hulud was also the fault of "the others" :P

@bazkie Yeah, I understand. But I am afraid this is never gonna change. It may be a bit like in the offline world: When walking on the street, It's much easier to find food than information on nutrition. To find a such information, you would probably go to the university, or go find a book in the library.
Likewise, there are places where you go for information online. As you're dutch, you may visit, e.g., tweakers.net for certain info, wikipedia or some subreddit for something else.
Moving Beyond the NPM elliptic Package
If you're in a hurry, head on over to soatok/elliptic-to-noble and follow the instructions in the README in order to remove the elliptic package from your project and all dependencies in node_modules. Art: CMYKat Why replace the elliptic package? Yesterday, the Trail of Bits blog published a post about finding cryptographic bugs in the elliptic library (a Javascript package on NPM) by using the Wycheproof.

The #JS utility you never knew you needed 😂
Create multiple Symbols in one go with this Proxy-based one liner.
“But aren’t proxies super slow?”
Nah. Depending on the browser it ranges from 50% slower to exactly the same.
Which unless you’re creating millions of symbols, is inconsequential.
In today’s episode of Useless Info I just learned about #JS:
Turns out you cannot subclass Proxy (because it has no prototype).
Nice try Lea 🥲
(Yes, I know that for this particular use case you can have a regular constructor return a Proxy)
#JS folks, what have you needed JS class mixins/traits for?
Especially interested in use cases outside of Web Components (I already have plenty around WC)
🥊 React vs Backbone in 2025
｢ The Backbone code is brutally honest about what it's doing. An event fires, a handler runs, you build some HTML, you put it in the DOM. It's verbose, sure, but there's no mystery. A junior developer can trace exactly what happens and when. The mental model is straightforward: "when this happens, do this."
The React code hides a lot ｣
»Math.random() is not so random — The Illusion of Randomness in JavaScript:
Don’t Trust Math.random() - Uncovering the Hidden Predictability of Random Numbers.«
In some applications random numbers are very useful but not unique and therefore you should consider where to use it. In this regard, there are for example, UUID v4 or Nano ID and the same.

@xenodium @stebalien casual-timezone uses the local zoneinfo DB which provides a local-first solution, avoiding a network call. The downside is that the zoneinfo DB only has a subset of all cities. The plus side is that zoneinfo DB updates are picked up for free by casual-timezone.
Question …
For our fedi software I did a "splitting parer" and am unsure about the dates portion https://gist.github.com/sebilasse/77ab52bb4ad82a9665f910a174c6ad90
When I write
"Bin morgen um zwanzig vor eins in Sydney" and pare it in 'de-DE'
[same like "Am tomorrow at twenty to one in Sydney" in 'en'] and spits it into an array
"Bin" and an ActivityPub Event for the rest with the time in Sydney (or whererever).
While all dates are stored in UTC internally it converts it with JS Intl to Sydney time.
But whats happens when a time-shift occurs within the difference to UTC, do I have to check reverse anytime ?
Any ideas?
@kickingvegas @xenodium @stebalien
just btw,
in #JS I am using https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl which also „provides a local-first solution, avoiding a network call“, just described in this thread 😊 https://digitalcourage.social/@sl007/115417827119273505
I mean, also just a subset whi I extended a bit by always being able to parse countries, all capitals and most populated (which are missing as Olson Indentifier).
Serverside it is very healthy that most countries only have 1 timezone. so any city within has it (just 2 gets)
