One thing I forgot to mention during my talk is that the replacement of 3rd party libraries with built-in Node.js features is the ultimate recognition for OSS involvement.

If you need CFP rejection emails content for training data, hit me up, I got loads of them 😎

I'm delighted with TS 7, but it's hard to be _that_ excited when there's no provision yet for type-checking Vue, Lit, Svelte, etc I'm watching this issue: github.com/microsoft/ty...

New post: "The AI Strategy Trap" Many orgs are rushing to embed AI for improved productivity, lower costs and more profit. But, they might be rushing into a costly dependency on a technology, with no say in the terms of the lease! www.craigabbott.co.uk/blog/2026/th... #ai #strategy #aiStrategy

A short article on the perils of the old JS Date API by @philna.sh 📜 It explains the modern solution: use Temporal which shipped in Chrome 144 yesterday 👍 And the article is already out of date! 😉 (in a good way - the article was published 24 hours before Chrome shipped)

I rebuilt my website as a Windows 95 experience. Try the Disk Defragmenter! #Wes95 #BuildInPublic https://wes.dev/

👋 Who is doing full on development with @bunjavascript ? I'm looking for someone who has committed to adopting Bun for their JavaScript backend to read my Bun Security Essentials book/course and write a foreword A general opinion / generic review is also ok Hit me up on DMs

Social media has ruined web dev the EXACT same way that it ruined politics. If there were elections in tech, it would be down to a few very popular but completely unqualified candidates who would each have their followers believing they were the "best", and then we'd elect a moron.

Web performance advent calendar calendar is upon us and I need contributions. What did you learn this year? Research, tools, case studies, wishes, aspirations, rants - all welcome! calendar.perfplanet.com/contribute/

We have hired lawyers and we have a draft of the trademark cancellation petition ready (for those who don't know about this, see javascript.tm)

Conferences have starter packs for their speakers, but it would also be great if we speakers/attendees made a starter pack of conferences! If it doesn't exist yet I'll create one later: which ones have Bluesky accounts? :)

I'm now an invited expert for TC39, around community+ecosystem tooling. Very excited to give perspective on great tools like linters to the committee. Huge shoutout & thanks to @nicr.dev for pushing for my & other tooling folks to be involved in TC39! ❤️‍🔥

So, we made a starter pack with all the amazing folks that had talks over the years at #JSHeroes! Who are we missing? Please let us know if we didn't find you but you are already here.

You know what I really missed about working for a company? Annual performance reviews & self assessments! So I wrote my own reflections for 2023. 🥰 It was a really, really fun year - and exhausting. www.joshuakgoldberg.com/blog/2023-in...
