We just published the first episode in a new series, "Developer Mode", on the Chrome for Developers YouTube channel: www.youtube.com/watch?v=Wkhl...
I'm really excited about this one. We're experimenting with the style and trying to focus more on developer questions.

Neat lil learning from today’s @perfnow.nl (via Umar Hansa):
You can now throttle individual requests in Chrome!
Neat for experimenting with stuff like
- lazy-loading: does the UI look okay if this chunk takes MUCH longer to arrive
- resilience: what happens if this specific CDN is extremely slow

Please, please don't use `font-display: swap` with icon fonts. I mean, as a rule, don't use icon fonts — SVGs are so much better — but if you must, then don't use `swap`. It doesn't make sense to see random fallback letters for icons.
Do me a favour and check your site now if using icon fonts.

📝 Importing vs fetching JSON
JSON imports are now supported cross-browser, but when would you use them rather than fetch()?

Match URLs with a powerful, standardized syntax using the URL Pattern API → goo.gle/47iTr3o
Now part of Baseline, this API provides a built-in way to create URL pattern matchers that can be used against URLs or individual URL components.

So, here's a web app where you can rank the proposals you care about, giving us data we can use when reviewing which ones to champion.
