Great piece, OP. We work in WASM and are considering web workers to help with rendering documents off the main thread in that context. I was surprised to read that ArrayBuffer is moved by reference only! Might be an option. Thanks for putting this together.
One thing that I found quite interesting to see is how the behaviour of the "4.000 particles" demo changes between the 5ms rendering and the "everything now" rendering.
Yeah, but if your website with, you know, text and stuff, doesn't do any stupid and unnecessary crap, it doesn't matter where the nonexistent unnecessary yet expensive code doesn't run.
and if you have no website at all, it takes zero seconds to load.
But for people who are developing websites that are more than just text, this is an excellently written article and great advice.
It's funny, for mobile app dev it feels like the community are a lot of focused on staying off the main thread, this is the first time I've come across one for webdev.
Well yeah but if you do actually need things like images, animations, high frequency updates, etc, this is actually a pretty good overview of how to approach it. Also learned that react uses posting to a MessageChannel to yield!
GP is right that just like with garbage where "reduce, reuse, recycle" the first question for optimizing something should be if you need to do the calculation at all.
This is true as well, yeah, but it came off as dismissive of everything too. Personally I prefer information dense interfaces with minimal chrome, but there really is a certain joy when you get to use a well designed and optimized fancy reactive, immersive interface
Amazing how you are being so down voted, most webpages do utter crap that no one would want the webpages to be doing other then advertisers. Really most things should be text and if we lived in a more cooperative world everything would be easy to parse and manipulate text with some video and images and perhaps various well defined interface types for different services that can be implemented in various ways as to the users liking.
My point is that many websites are using way too much technology for what they need to do, with correspondingly long load times and choppy runtime begavior.

Excellent article, I went into it thinking the headline is obvious, but the examples are well crafted and it isn't just the obvious stuff.
In the first example: doesn't pushing the button while typing cause the textfield lose focus? What's the point of the typing in the example?
I think the point is, if you click the '2.0s' button, you cannot re-focus on the input field for those 2 seconds.
Nice examples, a bit repetetive perhaps.

I wish await in JavaScript could conditionally yield. Instead I end up having to use arounds like if (shouldYield()) await do yield();
There's an RFC or two to spawn threads so I'm looking forward to that. The current way of workers + messages is tedious as hell.
Such an excellently written articles with really nice interactive visualizations!

Sure, but there are sites like HN and there are sites like https://earth.nullschool.net/
What's your point? Are you saying all animations and rendering are unnecessary?
