Low-key hating the fact that #TypeScript does indeed type check the arguments to Array.prototype.includes(), Set.prototype.has() and the like.

const things = [1, "a", false];

// (╯°□°)╯︵ ┻━┻
if (things.includes(null)) {
}

Joke's on me: the conference has 4 AI tracks, one for Blockchain (!) and bunch of backend/culture stuff. Nothing for straight up JS 🤡

I am apparently going full joker for this next round of #webdev and #javascript conference CfPs.

Extreme Rules Lawyering with the ECMAScript Specifications

Nerds all over the galaxy agree: TECHNICALLY correct is the best kind of correct! So why not mine the ECMAScript specifications for some technically valid JavaScript programs that “work”, but only by exploiting a wide variety of obscure semantic loopholes on the way? This talk goes far beyond mere syntactical obfuscation and explores the absolute fringes of JavaScript—for fun and for very, very little profit. Let us summon forbidden objects, unearth unholy functions that are not meant to be developer-accessible, and abuse features that TC39 would REALLY like to sweep under the rug.

Anybody can follow “best practices” and write “readable code”, so how about learning something actually new and unique? This session will instantly turn you into a living and breathing JavaScript infohazard, uniquely able to conjure up valid JavaScript programs that even ChatGPT could not hallucinate.

The quick and dirty #PWA that serves as my timer app for talks is 260 LOC JS (excluding the auto-generated service worker). This is simultaneously not much and quite a lot. But it would be SO MUCH MORE without the Temporal and Intl APIs! Truly game-changing additions to #JavaScript!

I need a derogatory term for moderately unhinged LLM enthusiasts that does not _immediately_ warrant challenging me to a duel. Cogsucker and botlicker are just too spicy for some use cases. Is there any established, but only mildly offensive term for that sort of guy?

Started to add dashes to the names of all the custom events that I make up. This is not strictly required, but like with custom elements, it removes the risk of collision with new standards and makes custom and built-in events easy to tell apart.

#webdev #JavaScript #webcomponents

JavaScript class method definition:

@listen("click", "button[data-value]")
#handleQuickPick(evt) {
this.dispatchEvent(
Object.assign(new Event("gutter-editor-pick"), {
value: evt.target.dataset.value,
}),
);
}

🤡 The so-called "International _JavaScript_ Conference" sports a track for Angular and a track for React.

Also there's a track for AI Devtools, one for GenAI & Agents (not to be confused with "GenAI and LLMs", which is its own separate track) and also AI Strategy and AI Governance of course.

Yeah.

Idly fact-checking MDN (as you do) yields more superb error messages: "cannot directly construct builtin %TypedArray%"

Browsers are so bad at this. This is FF, but Chrome's "Abstract class TypedArray not directly constructable" is not better.

#webdev #JavaScript

Firefox reporting "Uncaught TypeError: cannot directly construct builtin %TypedArray%" when I try to coax a naked TypedArray into existence (which is supposed to be impossible)
