A Report on How the Web is Really Using JavaScript
Each year, the HTTP Archive puts together the Web Almanac, a report on the ‘state of the Web’. The JavaScript section has just gone live and goes into depth on how much JS we’re using (or failing to use!), the popularity of TypeScript, loading methods, Web Worker use, and, yes, jQuery still leads the way! - https://almanac.httparchive.org/en/2024/javascript

The Many, Many, Many JavaScript Runtimes of the Last Decade
A meaty article (which took a year to put together) covering the myriad of JavaScript runtimes and engines both past and present, from obvious picks like Node.js to cloud platforms and lesser known ‘honorable mentions’. This is a great summary to round out your JS ecosystem knowledge. - https://buttondown.com/whatever_jamie/archive/the-many-many-many-javascript-runtimes-of-the-last-decade/

UI algorithms: a tiny undo stack
I’ve needed this before - a couple of times. Third time I figured I needed something small, nimble - yet complete. And - at the same time - wondering about how to do it in a very simple manner. I think it worked out great, so let’s dig in. Most UIs will have…

I Think the Ergonomics of Generators is Growing on Me

I think the ergonomics of generators is growing on me.
I took a stab at getting more familiar with iterators, iterables, and generators. I think I'm starting to like the ergonomics.
