You probably don’t need `aria-label` for that thing.
It doesn’t auto-translate:
adrianroselli.com/2019/11/aria...
It’s code smell:

You can probably use better methods:

aria-label is a code smell
If it is important enough to need words, it is important enough to use text content..

I really like to see those coming proposals to not have to generate arrays just to get a number at the end
It also fits a proposal I've been trying to push: github.com/Ayc0/proposa... that has the exact same goal: not rely on Object.entries() when it's not needed

❌ If you unit-test a React 19 app, there’s a good chance a chunk of your CI time is being wasted on… 😴 setTimeout.
Wait, what? Yes!
React 19 introduced a minimum delay for showing a Suspense fallback, and hardcoded (!) it to 300ms.
Just 3 tests can waste almost 1 second on absolutely nothing!

🤩 There’s a very – VERY! – exciting animations/performance change available in Chrome Canary:
Under the right conditions, `width`/`height` animations will no longer automatically force a Main Thread animation, but can be allowed to run on the Compositor.

This is quite a banger feature for web perf engineers. In Chrome Canary, you can now turn on an experimental feature to throttle single requests!
