"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?

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 🤯
