Huge thank you and congrats to @domfarolino.com ❤️
I've helped / worked on / watched this through different standards bodies for more than 10 years now. ☠️
(I'm going to have a lot of work now to adapt RxJS to this 😅)

🚨PSA: When copying GitHub URLs, always hit "Y" first!
Hitting "Y" adds the current SHA to the URL. This ensures your link doesn't break as the repository changes over time.

I'm not sure why I never realized this, but it makes sense.
JSX doesn't treat new lines in text the same way that the browser interprets them in HTML text content
It's just interesting, in HTML the outcomes below would be the same.

Progress photos part 2:
I used a simple 3 color palette: Ultramarine blue, cadmium yellow light, and alizarin crimson.
I used a relatively thin medium for the lower layers: 2:1 turpenoid to safflower oil. Getting heavier with more raw paint as I worked up.

This is the first oil painting I've finished in 25 years. A long overdue gift for my parents.
Although there's a lot to improve, I've never been happier with a painting. I'm not really an "artist" anymore, but a hobbyist. So I'll take it

#TypeScript PSA: If you're using `for..of` to do all of your iteration, you don't need to pass/type things as Array, use Iterable!
`for..of` does iteration, so any Iterable will work.
Passing `Item[]` here would be a unnecessarily restrictive:

I'm very impressed by Microsoft Edge's built-in shopping features. If you browse to an item on a retail site, Edge will give you price trend information and prices for other retailers! Super handy, IMO.

It's been ages, but I swear that sometime in 2017 or so, @danr.bsky.social (TS team) told me "Use interfaces, not types, for objects". I've also seen people whom I trust less tell everyone to "use types, not interfaces".

I guess I don't spell Shawarma very often... Also, I feel like when that's what I'm ordering, I already know it's what I want when I walk in, so I probably don't even really read the menu. 🤔

Okay... here's a primitive example.
Let's say that the expected version number updates 3 times in a row, but the actual only updates 1 time after all of that.
What's ACTUALLY rendered here only changed twice. Which is fine in isolation.
But the component has a lot of other hooks/logic to execute.

And after looking through some GraphQL related stuff, I decided to checkout tRPC's offering for streaming data... and look! Another observable implementation. No RxJS here.

More observables in the wild.
Note that there's no RxJS here. That observable is yet another flavor of observable. This time from Facebook's Relay library.
