Support useTransition/startTransition/Suspense?

[fr-an-k]

Can React 18 concurrency features be added to Fre? Or realized in a different way?
In other words, 1) does Fre support expensive state computation while remaining snappy? 2) Is there a built-in mechanism to get the pending state?

1. does Fre support expensive state computation while remaining snappy?

Yes, of course.

2. Is there a built-in mechanism to get the pending state?

It is more difficult to implement suspend in fre than react, because the diff algorithm of fre is more complex. I haven't had much time recently, and I may come back in the future。

Four years later, I updated and the current Suspense implementation is correct. I disappeared for four years and now occasionally appear.
Transition is currently not supported because Fre does not have a priority mechanism. Next, I plan to support fre server component.
