... and we immediately get sidetracked with solving actual production problems via less-known #javascript features. As usual!

This week's workshop comes without travel blogging because it's not at the other side of the country, for a change!

The only real downside of oklch() is that you first have to beat everyone around you into submission #css #webdev

Somebody should build a fake react docs generator, like this one for git: git-man-page-generator.lokaltog.net

Git man page generator

Create an infinite amount of straightforward and readable git manual pages.

The plan was to just modularize language loading in Code.Movie's online playground. Now there is basically no pixel where it was before 🫠

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.
