⚓ Oxlint now supports plugins written in JavaScript ⚓
Developers can customize and extend Oxlint using JavaScript, but at a speed approaching Rust, due to 'raw transfer' between Rust and JS, and other breakthroughs
Many ESLint plugins can run without any modification.

I would like @tc39.es to try this
As an experiment, we (the Firefox team) wanted to try a new way to get feedback on which Interop proposals matter most.
So, here's a web app where you can rank the proposals you care about, giving us data we can use when reviewing which ones to champion.

Trying to fix tablemark-cli's tests in CI... I know it's color related but setting `FORCE_COLOR` to 1 in Vitest config `env` didn't work. Can't repro locally unless I set `FORCE_COLOR` to 0. Ideally the snapshots would include colors
CI fail:

I'm clearly doing something Turbopack doesn't like, because I'm not seeing anywhere close to the compile times or perf gains I'm hearing about in Next.js. I miss Vite 🥺

Integrated @arktype.io into my haltcase.dev/run script runner. Silly example, but it makes writing handy reusable scripts type-safe _and_ delightful 😁
![TypeScript code using the `@haltcase/run` and `arktype` libraries:
import { task } from "@haltcase/run";
import { type } from "arktype";
const schema = type({
name: "string",
class: "'Barbarian' | 'Rogue' | 'Wizard' = 'Rogue'",
armorClass: "string.numeric.parse",
env: {
"SECRET_GMS_WEAKNESS?": "string"
}
});
export const printCharacter = task.strict(
schema,
async ({ env, name, armorClass, class: characterClass }) => {
console.log([
`🎲 ${name}`,
`⚔️ ${characterClass}`,
`🛡️ ${armorClass}`
].join("\n"));
if (env.SECRET_GMS_WEAKNESS) {
console.log(`${env.SECRET_GMS_WEAKNESS} makes ${name} king!`);
}
}

ECMAScript excitement 😉
TypeScript's @chronicles.org is pitching enum in JS 🎉
It's the good parts of TS enum + enhancements:
🔶 More datatypes: Symbols etc
🔶 Iterable
🔶 Immutable
🔶 Null prototype
🔶 No declaration merging
🔶 Compatible with Node type-stripping 👍

I started migrating off corepack when it introduced signature errors into all my builds (nodejs/corepack#612). Switched to @pnpm.io's ability to manage its own version 👌
Corepack's imperfect but was maybe the best hope for reducing package manager fragmentation? Bummer to see it die
