But it isn't wrong, is it? Democracy elected Hitler, Hitler ended democracy in Germany. I'm not saying that is going to happen here, but your flippant comeback to a valid point is not a rebuttal.

No - CSS and JavaScript are two ways of defining the same thing, an animation. Safari runs its accelerated animations with CoreAnimation - is CoreAnimation a CSS animation?

The UK has been described as an Eastern European economy with London bolted on. Poverty is very obviously increasing there, for anyone familiar with the country.

Most CSS animations aren't hardware accelerated. Only a few values like opacity and transform.

Updating the DOM (as in innerHTML) is always expensive because it triggers layout. This is true whether you're doing it from JS or a CSS trick like on this page.

Finally this approach is using CSS custom properties. These are slow - slower than JS for most things.

If you stop all animations on this page and profile it via Chrome you can see this in effect. The root node is animating a CSS variable. 117 elements have their style recalculated. Every frame - yet no animations are running. There's also a tiny paint triggered too, obviously there's been no changes so it is tiny in this instance, but a paint is always triggered when a CSS variable updates.

This is why animating x and y separately via CSS and a style like `translate(var(--x) var(--y))` would be worse than animating them via JS ala Framer Motion/GSAP.

If that's the book I'm thinking of I was also initially impressed until like chapter 6 when, after spending the book talking about how simple and elegant this theory was, it opens with "what if there wasn't just one string but lots of strings, and they were n-dimensional etc etc..." and threw it all out the window. I put the book down.

Not really - watches are historically round because of roundrel clock faces. A square is a better form factor for literally everything else that an Apple Watch does. So it is the Apple move to shape the watch to perform best at 95% of its tasks, and a Google move to shape the watch to perform best with a subset of available watch faces.

This isn't even new. Casio etc have designed digital square watches for decades because they don't need to be round without clock arms.

Because the screens are shit, comparatively. Also the OS is years behind.

They might carry on improving the quality for the Pro (although this also has limits and diminishing returns) but they don't need to do that if they're targeting a sub $1000 headset, they just need to make these screens cheaper.

If you add a x scale of ~2.3 on the logo it's clear they just took the whole thing and scaled it down. Looks so much better.

Yes and no - IE was hated in part for deviating from standard/showing weird behaviour. But more than that it was dragging its feet on implementing new CSS and JS standards so they couldn't be used for years after introduction. It was nightmare.

I mean the library is like a decade old so "finally back" is a stretch

Your intuition is correct - there's nothing to indicate any delay.

Look at your profiler. Notice any significant overhead? You don't.

Implement this same thing using events and `.style` directly. You will get the exact same result.

The pointerEvent => style feedback loop is unfortunately very slow, more or less so in different browsers/operating systems.

Interesting that you would know so little about this and yet feel confident enough to make a proclamation like this is evidence of React's performance.

Interesting you assume they didn't consider this. They probably did.

How do this two behaviours compose together/interact with each other?

> It seems the US and allies no longer just wants UA to hold their own against RU, but actually win the war

There is no "hold their own". This would be a state of perpetual warfare. The only way to end the war is to allow Russia to claim Ukraine or push Russia out of Ukraine. Personally I would rather the Russian border to be as far east as possible.

I believe these are the AR glasses, not the mixed-reality headset supposedly coming this year.
