tl;dr; JavaScript DOM nodes are just handles to Blink DOM nodes. The article doesn't peek under the hood tbh. If you want to look under the hood you should analyze the Blink implementation.

Not my area, please post more links. Here are the first two that I found that gave a bit of an introduction to the topic.

No relation to the <blink/> tag, I presume?

Blink is Chrome’s rendering engine, originally forked from Webkit. Interestingly, it is indeed named after the blink tag.

Interesting. How is the concurrency achieved? I don’t see any info about concurrency implementation on the website

Some info on this page: https://lfi.dev/docs/concepts/concurrent-iterable

Recommend reading it all, but this part is probably most useful: https://lfi.dev/docs/concepts/concurrent-iterable#how-does-i...

Ok. So it’s all single threaded, right? Then it only looks like run concurrently from the consumer side. There’s no actual work being done at the same time

Fun stuff
