Oops, I accidentally added type checking for code blocks in regular markdown files in addition to MDX. Ah well…

Frontend engineer at @datadoghq Personal website: https://ayc0.dev/ I try to build good tools for #javascript and #reactjs 😅
The @react.dev compiler landed in Oxc (thanks @boshen.github.io) 🎉 It is 2x faster than the initial Rust port while being 2x smaller and comes with granular rule support for Oxlint, improved diagnostics messages, and an *optional* transform for @vite.dev (integration with the React plugin pending)

I really need to start doing fewer things at the same time. It’s not healthy, and I’m not really “faster” this way. Been working concurrently on 4 different PRs for days and it’s killing me 💀
ECMAScript excitement 😉 Congrats to my coworker @ashley-c.bsky.social at TechAtBloomberg on advancing Await Dictionary to Stage 3 at TC39 🎉 Promise.all returns positional results as an array. Promise.allKeyed allows named results inside an object 👍 github.com/tc39/proposa...
@mu.social does "mu" have a specific meaning? Like an acronym or a pun on "eusocial"?

Threw together something I've wanted for awhile: mdx-tsc Typecheck your MDX files just like you do other TS. Validate in CI Plus: - Typed frontmatters. Errors on both defintions and usage - A VSCode extension that add intellisense, go to def, etc for frontmatters npmx.dev/package/mdx-...
I just merged a PR in one of my repositories (see github.com/Ayc0/ayc0.gi...). But, the merge commit doesn't appear in main. And when checking the exact commit (github.com/Ayc0/ayc0.gi...), it says that it doesn't belong to any branch on this repository. Like what????
Buying a new domain name with @marque.at is quite easy! The process takes just a few minutes, and they update your BlueSky handle for you That's quite neat 👌
The other day, I was talking to a colleague about how to generate an unique UUIID for a react component instance. I figured it could be a good idea for a blog post. So I decided to write one 😁 ayc0.github.io/posts/consta...
React: how to define a constant variable
When working with components, a use-case comes up often: computing an operation on component initial mount, and having it be fully stable across the entire lifetime of the component

Le climatologue Christophe Cassou est harcelé depuis 48H suite à son passage sur BFM TV. Un extrait vidéo coupé sur X, qui oublie une partie importante du discours, et des milliers de personnes lui tombent dessus. Pire encore, le député RN Tanguy en a profité pour le comparer à un dictateur.

It’s still the same: no semantic guarantee, only a performance improvement, your code should work exactly the same when useMemo is removed. If anything, offscreen rendering (<Activity>) will lead to more memos being thrown away.
@react.dev in the old docs for useMemo (legacy.reactjs.org/docs/hooks-r...), you could read: > In the future, React may choose to “forget” some previously memoized values and recalculate them on next render But I can’t find any similar mentions of this in the new ones in react.dev/reference/re...

temporal-polyfill 🕒 1.0 is out! Smaller and with a tree-shakeable API that can be codemodded away. Great for component lib authors: tiny footprint now, zero footprint later, and shared internals with the host app's polyfill (if they choose to install it).
