Friday Links #33 — Fresh JavaScript Tools & Trends
A curated weekly digest of new libraries, releases, and ecosystem shifts shaping the modern JavaScript landscape.
The JavaScript ecosystem evolves quickly — new tools land, frameworks ship updates, and experiments turn into production-ready solutions overnight. Friday Links is your weekly shortcut through that noise: a focused snapshot of what’s worth paying attention to right now, without endless scrolling through timelines and repos.
Welcome to issue #33, covering the latest releases, interesting utilities, and trends in the JS world.
OpenAI Launches ChatGPT Health
OpenAI has introduced ChatGPT Health, a dedicated section inside ChatGPT focused entirely on personal health. It’s more than a themed chat — users can discuss symptoms, interpret lab results, track metrics over time, and get clear explanations of medical terms.
A key feature is integration with health and fitness services. Users can connect Apple Health, MyFitnessPal, and similar apps so the AI can analyze sleep, activity, nutrition, and wellness trends. In the U.S., it can also sync with electronic health records for reviewing test results and medical history.
Privacy is a major emphasis: ChatGPT Health uses separate infrastructure with layered encryption, and its data is not used to train base models or mixed with regular chats by default.

🗞️ News & Updates
Google AI and Vercel Sponsor Tailwind After 80% Revenue Drop Caused by AI
Logan Kilpatrick, Head of Product at Google AI Studio, posted on X that the Google AI team is now a Tailwind sponsor and added:
“I’d love to discuss how we can do more together.”
Guillermo Rauch, CEO of Vercel, also confirmed sponsorship.
Why It Happened
According to Wathan, the crisis was caused by a broken sales funnel. Previously:
developers googled CSS questions,
landed on Tailwind’s documentation,
discovered paid products like component kits and templates.
With modern LLMs such as Claude, ChatGPT, and Cursor, developers now generate code directly. Since LLMs were trained on Tailwind documentation, they produce accurate solutions without the developer visiting the site.
The result:
documentation traffic dropped 40% since early 2023
Tailwind reached 75 million downloads/month, making it more popular than ever
revenue collapsed despite adoption increasing
How Much Sponsorship Was Provided?
Google and Vercel did not disclose amounts. Tailwind’s public sponsorship tiers start at:
$6,000/year (base tier)
$60,000/year (top partner tier)
Before today, Tailwind already received ≈$1.1M/year from 29 corporate sponsors, including Cursor. Despite that, layoffs were unavoidable — only one engineer remains from the original four.
For now, three engineers have already lost their jobs, new sponsorship sums remain undisclosed, and only time will tell whether this was a one-time PR move or the start of systemic open-source funding from AI companies.
OpenAI, Anthropic, and Google Share the Top Spot in Intelligence Index 4.0
The platform Artificial Analysis has published the fourth edition of its Intelligence Index, one of the strictest rankings of modern AI models. In this update, the report recorded an effective three-way tie between the largest players. Formally, GPT-5.2 (X-High) takes first place, but Claude Opus 4.5 from Anthropic and Gemini 3 Pro from Google trail by only a statistically insignificant margin.
The key change in version 4.0 is methodology. The authors deliberately toughened evaluation criteria and abandoned the familiar benchmarks that models have become highly optimized for in recent years. As a result, absolute scores dropped: where leaders previously scored above 70, the new ceiling is closer to 50. This isn’t model degradation — it’s an attempt to restore genuine difficulty to the measurements.
Micro QuickJS: a JavaScript Engine for Embedded Devices Using Only 10 KB of RAM
Fabrice Bellard — creator of QEMU, FFmpeg, QuickJS, TinyGL, and TinyCC — has introduced Micro QuickJS, an open-source JavaScript engine designed for embedded systems. It can compile and execute JavaScript programs with as little as 10 KB of RAM. The codebase is written in C and published on GitHub under the MIT license.
The results of the State of HTML 2025 survey are now available.
That’s a wrap for this week’s edition. If you discovered something useful, share it with teammates or send in a link you think deserves a spotlight next time. The JS ecosystem thrives through learning, remixing, and curiosity — see you next Friday for more tools, updates, and ideas.
