"There is no syntactic means to create instances of GeneratorFunction subclasses" says the ECMAScript specification. Well, if you just call your new constructor it works fine ¯\_(ツ)_/¯

#javascript #webdev
class GenFnSubclass extends (function*(){}).constructor {} const instance = new GenFnSubclass("yield 23"); instance instanceof GenFnSubclass returns true

Sure, let's start the new talk with this slide.
function whatever(a, b) {} whatever[0] = 23; whatever[1] = 42; Object.setPrototypeOf(whatever, Array.prototype); whatever.forEach((value) => { console.log(value); });

Code.Movie 0.0.37 now supports static syntax highlighting to supplement the existing animation features. Some CSS improvements are also along for the ride.

📝 Post: code.movie/blog/static-...

📦 Package: www.npmjs.com/package/@cod...
import { highlightHTML } from "@codemovie/code-movie"; import { json } from "@codemovie/code-movie/language/json"; document.body.innerHTML += highlightHTML({ code: "[23, 42]" }, { language: json(), tabSize: 2, // other options are the same as for animateHTML() });

What's worse: no documentation or AI-generated documentation?

Failed to photograph an adorable kingfisher on the #kiel canal today. Here's some boats and scenery instead.

Compiling the core of code.movie plus all the language modules with code splitting (via esbuild) yields about 977.2 kb of JS in total. Without code splitting? 5.3 mb 🤯
