📄 jQuery 3.7.0 Released

JavaScript Weekly is 638 issues old, or almost 13 years once you take away weeks off, so jQuery was a big deal in our early days. We hold a lot of nostalgia for it, and it remains widely used even if no-one is writing about it anymore v3.7 folds the Sizzle selector engine into the core, adds some unitless CSS properties, gains a new uniqueSort method, and “major changes” are still promised in future. jQuery lives on!

🔩 Starry Night: GitHub-Like Syntax Highlighting

Apparently, GitHub’s own syntax highlighting approach isn’t open source, but this takes a similar approach and is. It’s admittedly quite 'heavy' (due to using a WASM build of the Oniguruma regex engine) but that’s the price of quality.
