Congrats to @manishearth.bsky.social on unflagging TC39 Stage 3 Temporal in V8 today. Heading for Chrome 144 🎉
By many metrics this new date-time API is the single biggest change to JS ever 🔥

We're reaching full support (experimental) for Vue, Svelte and Astro in @biomejs.dev! I just finished implementing the application of code fixes inside embedded languages :)
If everything goes well (it depends on what the team decides), it will be shipped in the next minor.

pnpm v10.16.0 adds "minimumReleaseAge", a setting for defining how long a version has to have been published before pnpm will install it.
A nice countermeasure against accidental installs of short-lived compromised packages before they get taken down. Not a 100% fix, but a great additional step!

TypeScript excitement 😉
TS 6.0 is planning a bunch of breaking changes to tsconfig options to deprecate some and change the defaults for others. This will simplify configuration and ease the transition to the Go-based TS 7.0 👍
The latest pitch is to enable strict type-checking modes by default 🎉

Just filed an issue to turn `--strict` on by default in TypeScript.
Maybe it's a little bit ambitious, but I'm excited for us to try this one. 😄

Let me take you on a visual introduction to what big O notation is in my new blog post: samwho.dev/big-o.
With big O notation you can better understand how algorithms will perform in practice, finding orders of magnitude improvements often with very simple changes to your code.

The semver library used in npm, yarn and pnpm could be made 33x faster.
Ran into that while wondering why running `npm install` takes so long on the Preact repo.

Speeding up the JavaScript ecosystem - Semver
During the installation process, package managers run a bunch of semver comparisons. The semver library used in npm, yarn and pnpm can be made around 33x faster.

Congrats to @marcoippolito.dev on today's landmark Node 22.18 release. It is the first LTS release to ship unflagged TypeScript support 🎉
This means Node can run *.ts files. It pairs well with TypeScript's "erasableSyntaxOnly" flag 👍
Many folk contributed 🙏

Type stripping is enabled by default 🔥🔥🔥🔥
You can just run `node file.ts` without `--experimental-strip-types` flag.
This is a huge milestone

Node.js 22.18.0 is out and enables type stripping by default – that’s right, Node.js LTS can now run TypeScript files. Shout out to @marcoippolito.dev for championing that effort! Download links and full changelog available at nodejs.org/en/blog/rele...
